  • So Above is a equipment list for cow dung and chicken manure npk compound fertilizer organic-inorganic production line, next we are going to introduce some of the details of the equipment and features/adventage of these equipment.
  • Of course you might notice that the conveyor system and hot air generator is not included in the above list, that is because the conveyor system we have two options, bucket elevator and belt conveyor, it is highly based on the site condition, therefore we did not include it in here.
  • Also the hot air generator or you call the hot blast stove is not in the list that is because different customer has different kinds of fuel, therefore some customer wants coal-fired, some customer wants natural gas fired, so we just leave it blank in here.  

Organic-inorganic 200,000 tons per year fertilizer production plant equipment introduction in detail:

Organic fertilizer fermentation tank:

  • The fermentation tank equipment adopts the principle of aerobic microbial aerobic fermentation, allowing microorganisms to utilize organic matter and residual proteins in livestock and poultry manure to reproduce rapidly under a certain temperature, humidity and sufficient oxygen environment. It can be used to process pig manure, chicken manure, cow manure, sheep manure, mushroom residue, crop straw and other organic waste.
  • After about 10 hours of continuous aerobic fermentation in a closed fermentation tank, the organic solid waste is processed by microorganisms. After fermentation, deodorization and decomposition, it is processed into high-quality organic fertilizer that can be used for crops.

Advantages of fermentation tanks:

  1. The equipment is small in size, can be installed outdoors, and does not require a factory building. It is a mobile processing factory, which solves the high cost problems of factory construction, long-distance transportation, and centralized processing;
  2. Sealed treatment, 99% deodorization, no pollution;
  3. Good thermal insulation, not subject to seasonal cold restrictions, and can be fermented normally in environments below minus 20 degrees Celsius;
  4. The fermentation cycle is about 15 days, and the processing capacity can be increased by installing multiple units as needed;
  5. Three-layer structure, good mechanical materials, solves the corrosion problem of strong acid and alkali, long service life, can be used for more than 10 years;
  6. Simple operation and management, input livestock manure and other raw materials, automatically produce organic fertilizer, easy to learn and operate;
  7. Low energy consumption, the average power consumption of a single FJG-86 device is only 22KW per hour;
  8. Aerobic bacteria can survive and reproduce at -25℃-80℃, and the beneficial bacteria formed can kill harmful bacteria in the raw materials.
  9. Using tongli’s latest technology, the original 20-hour fermentation process can be shortened to 9 hours.

Raw material storage buffer silo for chicken manure cow dung:

  • In fact, simply speaking, the role of the silo is to ensure that the production line runs continuously and does not stop due to interruption of raw materials;
  • In order to improve production efficiency, we configure a preparation silo in front of the crusher so that there is always a batch of fermented products. The materials are waiting to be crushed so that the organic fertilizer production line can have a continuous supply of raw materials. Secondly, the material will form an air arch and it is difficult to unload the material.
  • The unloading port of the silo is equipped with stirring teeth. The outlet of the silo can also be customized according to the customer’s raw materials.

The advantages of cattle, sheep and chicken manure raw material silos are as follows:

  1. In order to improve production efficiency, a preparation bin is installed in front of the crusher so that there is always
    Batch fermented materials are waiting for crushing, which can increase production efficiency by 80%.
  2. Secondly, the crushing and preparation of raw materials can be carried out even when the production line is not running.
    Enough raw materials.
  3. The forklift silo can reduce workers and reduce production costs.

Bulk crusher for semi-wet organic matter:

  • Semi-wet bulk material crusher is a new type of high-efficiency single-rotor reversible crusher. The high-speed rotating blade is used to crush the fiber, which has good particle size, high efficiency and energy, and strong adaptability to the moisture content of the material.
  • Especially for fermented decomposed garbage or other materials with moisture content ≤30%, it can be milled. The particle size of the powder can reach 20-30 mesh, which can meet the feeding particle size requirements of general fertilizer granulating equipment. Half;
  • Wet material crushers are mostly used in the production and processing of organic fertilizers to crush raw materials such as chicken manure and sodium humic acid.

The structure of organic fertilizer bulk crusher:

  1. The semi-wet material crusher adopts two-stage crushing. After the material is crushed by the upper cutting disc of the rotor, it is transported to the crushing chamber for secondary crushing by hammers, and finally discharged from the discharge port.
  2. The semi-wet material crusher is not designed with a screen bottom, which will not be blocked due to the crushing of wet materials, causing the motor to burn out and affecting production.
  3. The semi-wet material crusher uses a high-alloy wear-resistant hammer head, and the hammer blade is made of forging, which is particularly strong and wear-resistant. It is stronger and more wear-resistant than ordinary hammer heads, which increases the service life of the hammer blade.
  4. The semi-wet material crusher adopts two-way gap adjustment technology. If the hammer blade is worn, it does not need to be repaired. You can continue to use it by adjusting the position of the hammer blade.
  5. The semi-wet material crusher can be easily operated by only one person. It is not only safe and reliable, but also easy to maintain.
  • The organic matter bulk crushing machine can be divided into three parts:
  1. Frame part: The normal operation of all machinery is inseparable from a solid frame. The machine frame is all welded with high-quality carbon steel plates and channel steel, and has passed strict product certification and specific process requirements. To achieve the purpose for which this machine is used;
  2. Rotor crushing part: The rotor of this machine has a novel structure and reasonable design. It uses double-layer blades for crushing. The crushing effect is three times that of other products. The material enters the crushing chamber from the feed port and is continuously ground by the double-layer blades. The material meets the granulation requirements.
  3. Transmission connection part: This machine adopts flexible belt transmission. The motor drives the pulley and belt, which are directly transmitted to the main shaft, causing the main shaft to rotate at high speed to achieve the crushing effect.

Double shaft mixer-organic fertilizer special designed:

  • The twin-shaft mixer is equipped with reversely rotating paddles in the mixing area. The paddles are at a certain angle to
    The materials are circulated and stirred along the axial and radial directions to mix the materials quickly and evenly.
  • Mainly used in the process of pre-adding water to form balls. When a certain amount of raw meal powder flows into the mixing tank from the discharge port, it is sprayed to the raw meal powder through several water atomizers with a certain pressure, and is passed through a shaft with a fixed length. After stirring with the stirring blade, a ball core with consistent water content will be formed and transported to the pre-watered ball forming tray;
  • The entire stirring area is divided into three areas: atomization area, mixing area, and discharge area. The hard gold blade is welded on the mixing blade and has good wear resistance; it is suitable for mixing two or more fertilizers, additive premixes, compound feeds, concentrated feeds, additive premixed feeds, etc.

Organic fertilizer stirring teeth granulator

  • The organic fertilizer rapid granulator is also called a wet stirrer granulator and an internal rotating stirrer granulator. This granulator is the latest organic fertilizer granulator developed by Tongli.
  • Wet organic fertilizer granulator is widely used for granulating organic fertilizer. Due to the high granulation rate, smooth operation, sturdy and durable equipment, long service life, and the stable base design, it operates more smoothly, and is chosen as an ideal product by the majority of users. The specifications of the wet granulator are 1600 , 1800, 2000 and other specifications.

What is the working principle of stirring teeth granulator 2024?

  • The stir-tooth granulator uses the mechanical stirring force of high-speed rotation and the resulting aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powdery materials in the machine, thereby achieving the purpose of granulation. 
  • The particle shape is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%.
  • The size of the particle diameter can be adjusted appropriately through the mixing volume of the material and the spindle speed. Usually, the lower the mixing volume, the higher the speed. The higher it is, the smaller the particles are and vice versa.

Design considerations of stirring teeth granulator

  1. The stir-tooth granulator processes the organic raw materials after fermentation into granules. It overcomes the shortcomings of the disk granulator, which returns large amounts of material and is difficult to dry, and the flat film granulator, which has small output and cumbersome maintenance.
  2. All advantages are combined in one. The fermented raw materials are crushed before granulation. The ingredients are mixed directly with a mixer and fed into the wet granulator to process spherical granules. The granules produced by this machine are spherical, which greatly saves energy and improves utilization. Rate.
  3. Granules are directly processed from pure organic matter, and the characteristics of organic fertilizer raw materials are embedded and enlarged under certain effects.
  4. There is no need to add any additives, binders, etc. during granulation. After the finished product comes out, the granule strength is very good. It can be directly screened after granulation to reduce drying energy consumption and save coal and electricity.
  5. Reducing costs and increasing output are the biggest features of this machine. The stirrer granulator is suitable for processing organic fertilizer raw materials such as livestock and poultry manure, compost fertilizers, green manures, sea fertilizers, cake fertilizers, peat, soil fertilizers, three wastes, microorganisms and other municipal solid wastes.
  6. Specialty for granulating organic fermented fertilizer, the particles are irregular pellets.
  7. The qualified granulation rate of this machine is as high as 90%, and it is suitable for a variety of different formulas.
  8. The compressive strength of organic fertilizer is higher than that of disks and drums, and the large ball rate is less than 15%. The uniformity of particle size can be determined by this machine according to user requirements. Stepless speed adjustment function.
  9. This machine is most suitable for direct granulation of organic fertilizer after fermentation, saving the drying process and greatly reducing manufacturing costs.

Organic compound fertilizer rotary dryer

  • Tongli is the earliest manufacturer of compound fertilizer rotary dryers in China. Its history can be traced back to 1958. Tongli produced China’s first shotcrete granulation dryer and has maintained a leading position in the market for a long time.
  • Rotary dryers have a wide range of applications, easy operation, high output, and strong drying capabilities, and are widely used in the compound fertilizer industry.
  • In recent years, Tongli has cooperated with BASF and ThyssenKrupp to jointly develop a new generation of rotary dryers, which have been put into use in the market.
  • In order to achieve a uniform drying effect, Tongli’s lifting plate has a patented design. Tongli engineers use simulation software to reasonably distribute the number, position and angle of the lifting plates to achieve the best drying effect based on different tool working conditions.
  • The reason why Tongli’s dryers have long been ranked first in the market is that Tongli has 65+ years of production experience, has its own patented design, and is a leader in the compound fertilizer industry. Customers will not choose other manufacturers after using our products;
  • Tongli’s three most popular dryers in the compound fertilizer industry are the spray granulation dryer, the high-tower fully water-soluble compound fertilizer dryer, and the steam drum granulation dryer.

Organic compound fertilizer rotary dryer working mechanism principle:

What are the 3 main parts of a organic fertilizer rotary dryer?
  • First, let’s talk about the structure of the drum dryer, which can be divided into three parts. The support part is used to support the drum dryer, the transmission part is responsible for the rotation of the dryer, and the body part is the shell part of the drum dryer. But we have to emphasize one point here, a very important point, that is, the design temperature of the organic fertilizer dryer generally cannot exceed 150 degrees, otherwise the organic matter will be destroyed, and the fertilizer produced will be unqualified, so it must Pay attention to the design temperature of the dryer.
Dryer supporting device part:
  • The support part is composed of the dryer bottom frame, dryer supporting roller, riding ring, pinion shaft, etc. Its main function is to carry the weight of the entire dryer. Why tongli dryers are so good is because the support part is made of The size of the riding ring  and the size of the supporting roller are twice that of others. Why is Henan’s equipment so cheap? Because everything is half the size. Moreover, Tongli is one of the few compound fertilizer equipment manufacturers in the industry with the ability to cast steel, so the quality is certainly reliable.
Dryer transmission part device part:
  • The transmission part consists of two belts of the dryer, a girth gear, a pinion, a motor, and a reducer.

Rotary trommel/screening machine organic chicken manure cow dung

  • The drum screening machine is a commonly used equipment in the production of compound fertilizers. It is mainly used for finished products and returns.
  • The separation of materials can also realize the classification of products, so that the finished products can be evenly classified. The trommel screen is made of rollers
    It is composed of five parts: barrel, frame, funnel, reducer and motor.
  • After the material enters the drum from the feed port, it is screened as the drum rotates. On the other hand, the material with large particle size flows forward along the slope of the drum and is gradually screened out through the screens of different meshes. After the materials are screened out, they fall into their respective hoppers and are then transported out manually or by gravity to the finished product pile.
  • This machine adopts a combined screen, which is easy to maintain and replace. It has a simple structure, easy operation and smooth operation. It is an ideal equipment in the production of compound fertilizer.

  3. Transmission connection part: The motor drives the reducer through the coupling to make the main shaft rotate. The transmission reducer and the working part of the main machine are driven by pin-type couplings, which is convenient for assembly and maintenance. Small factories like to use pulleys in order to save costs, but the reliability is definitely not as good as the motor-coupling-reducer.
  4. The material enters from the feed end, continuously rotates and grades in the roller cage, and flows out evenly from the lower outlet, which effectively separates the finished product from the returned material, thereby reducing labor intensity;

Tongli ZJ series fertilizer chainmill aka chain crusher

  1. Tongli ZJ series chain crusher is suitable for crushing lumps in the production of compound fertilizers. It is also widely used in chemical industry, building materials, mining and other industries. This machine uses high-strength wear-resistant hardened steel with synchronous speed during the crushing process. Made of high-quality alloy chain plate, the inlet and outlet are reasonably designed, the broken materials are even, not easy to stick to the wall, and easy to clean.
  2. Why chainmill is important? becasue first of all raw materials after pre curshing using the bulk crusher above will send to chainmill, in the chain crusher, the raw material is further crushed and mixed together. Another important reaosn is that all the returning material that screen out from the screening process which using the rotary trommel and rotary screening machine, those material will be send back to the chainmill to be re-processing, so it serves the function like a “bus staion” where all the raw material organic-inorganic chicken manure and cow dung needs to pass through it to be processed.

Application of fertilizer chainmill aka chain crusher

  • The long-term use of the chain crusher proves that the machine is easy to use, has high efficiency, has large production capacity and is simple to maintain. Suitable for crushing all kinds of lump fertilizers and other medium-hard lump materials. The chain crusher can crush undried calcium phosphate fertilizer containing 14% water and 6% free acid and a variety of phosphophosphate compound fertilizer products. It overcomes the vertical chain crusher used by many domestic phosphate compound fertilizer manufacturers. Like other crushers, the material adheres to the inner wall of the casing during production operations, making production impossible.

Automatic-packaing machine for organic fertilizer granular

So in the form above we have already listed some of the features of our automatic packaging machine, so i will emphasis on one aspect that i did not mention in the form that this automatic packaging system is using a servo motor, which the speed is faster than the standard double cylinder packaging scale. Plus this automatic packaging system is equipped with SS304 conveyor, and is automatic sawing and stitching. So here is a concept we need to calrify here:

Power transformer dry type for cow dung npk fertilizer plant

  • Unlike other manufacturers, the transformers that Tongli equips customers with are dry-type transformers, which are much more expensive than traditional oil-immersed transformers. For the price of one dry-type transformer, you can buy three oil-immersed transformers of the same specifications. At the same time, Tongli uses The dry-type transformers are produced by companies listed on NASDAQ in the United States. Tongli organic fertilizer and chemical fertilizer factory dry-type transformer has the following advantages:
  1. Good environmental performance. Dry-type transformers do not require the use of insulating oil and therefore do not cause pollution to the environment.
  2. High fire safety. Since it does not contain flammable and explosive insulating oil, the risk of spontaneous combustion and explosion is small, which can effectively protect the safety of people and property on site.
  3. Low maintenance costs. Dry-type transformers do not require regular replacement of insulating oil, nor do they need to check oil contamination, making maintenance easier.
  4. Highly durable. Since no insulating oil is used, it can better resist environmental pollution and daily wear and tear, and has a longer service life.
  5. Simple structure and light weight. Dry-type transformers have a relatively simple structure, small size, light weight, and are more convenient and flexible to install.
  6. Low noise. The noise is lower at no load, and although the noise may increase when the load is high, it is still generally lower than the oil-immersed transformer.
  7. High efficiency. The winding is made of insulating materials, which improves the insulation performance. It also has good heat dissipation performance and reduces the temperature rise, thus improving the efficiency of the transformer.
  8. Automatic temperature monitoring and protection. It can monitor the temperature of the transformer in real time and provide protection in abnormal situations to increase safety.
  • The crusher we equipped in this organic fertilizer production line is a semi-wet material bulk crusher, which is mainly used for crushing chicken manure, cow manure, pig manure, sheep manure, and other organic materials with a moisture content of 25-30%. The crushing effect is excellent.
  • In the equipment configuration, Tongli is equipped with a new type of organic fertilizer granulator, which is mainly suitable for organic materials containing cellulose such as livestock and poultry manure, distiller’s grains, medicinal residues, biogas residues, wood powder, etc. It can be directly granulated with high pelletizing rate and high particle strength. Good, it saves drying costs, and the host does not need to be operated by a dedicated person during the production process.
  • After the fermented material enters the pulverizer and is ground into powder; the material is transported to the mixer and stirred evenly; after stirring evenly, it enters the organic granulator through the conveyor for granulation. The granules need to be sent into the dryer to remove moisture because of the relatively large moisture content;
  • After the particles come out of the dryer, the temperature is high. Since the condensed water produced by drying adheres to the surface of the particles, it is difficult to package and easy to agglomerate. Therefore, the cooler must be used to reduce the surface temperature of the particles by accelerating the air return flow and turn the condensed water into particles. Volatilizes into steam. This process can greatly promote the preservation effect of fertilizer and extend the preservation period;
  • After cooling, the particles still have different sizes. They have to pass through the drum screen. The particles that do not meet the standards must be crushed through the circulation outlet of the screening machine and then re-enter the granulator for granulation again. The particles that meet the standards can pass through the coating machine. and automatic packaging systems for wrapping and packaging.
  • So basically above is the equipment list and introduction of our organic cow dung and chicken manure production plant, we have introduced about the equipment feature as well as the specifications and design considerations, in our next article we will introduce about our other production line.

Design principles

In the design, try to use pollution-free or less-polluting advanced processes and equipment as much as possible. Strictly abide by the “Three Simultaneities” principle, all processes and equipment involved in this project that may produce pollutants will be treated with corresponding measures to ensure that they meet the standards.

Environmental conditions of construction site

This project is located in Dodoma Industrial Park. There are no cultural relics protection areas, schools, hospitals and other environmentally sensitive points near the project area. The air in this project area is fresh and the water quality is good, which is suitable for the implementation and construction of this project.

Atmospheric environment

  • The project area is surrounded by planned land and there are no industrial and mining enterprises with serious air pollution. After consulting relevant information, the daily average values of NO2, TSP, and SO2 in the project area all meet the Level II standard of the “Ambient Air Quality Standard” (GB3095-1996).

Acoustic environment quality

  • The acoustic environment surrounding the project area is of good quality. The surrounding environmental noise meets the requirements of the “Acoustic Environment Quality Standard” (GB3096-2008).

Water environment quality

  • There are no serious water pollution sources in the surrounding area of the project area. Except for the total number of bacteria in the surface water slightly exceeding the standard, the water quality is good, and the groundwater meets the requirements of Class III standards in the “Groundwater Quality Standards”. Therefore, the environmental status of the atmosphere and soil around the proposed project site is good and there is a certain environmental capacity.

Impact of project construction and production on the environment

Impact on ambient air during project implementation

  • Dust is the main pollutant that affects the ambient air during construction and comes from various unorganized emission sources. Among them, processes such as site cleaning, earth excavation, landfilling, and material transportation produce a large amount of dust, while processes such as material storage, construction of building structures, and equipment installation produce less dust or no dust. 
  • Moreover, dust is also affected by wind direction, wind speed, and humidity. and other weather conditions. Since the pollution sources are mostly intermittent and have low dust emission points, localized pollution will only form within a short distance. The pollutants generated during the construction period enter the ground breathing zone without being fully diffused and diluted, which will have a certain impact on the construction, life, health and safety of on-site personnel.

Impact on water environment during project implementation

  • The main sources of water pollution during the construction period are flushing wastewater in the construction area and domestic sewage of the construction team. Flushing wastewater mainly comes from the washing of building materials such as stones, and the main pollutants are SS; the main pollutants of domestic sewage are SS, BOD, COD, etc. But the good thing is Tongli has designed tail gas treatment system which is composed of tail gas washer tank, ventri washer, exhaust gas chimney so that the tail gas will be treated completely.
  • The discharge characteristics of flushing wastewater are intermittent discharge, and the amount of wastewater is unstable. During construction, water consumption is often uncontrolled and the amount of wastewater discharged is large. If no measures are taken, it will flow freely at the construction site, causing certain impacts on the surrounding water environment and landscape. Therefore the control of waste water duing construction period is within owner scope.

Impact of construction noise during project implementation

  • The noise during construction mainly comes from the transportation of construction machinery and building materials, the roar of vehicle motors and the noise of horns. The main impact on the surrounding environment during construction is construction noise, which has a wide radiation range, with a maximum distance of nearly 150 meters during the day and more serious impact at night.

Treatment and disposal of construction waste soil

  • The earthwork generated by construction excavation and the debris generated during the construction process must go through the procedures for the admission and disposal of construction waste with the municipal appearance and environmental sanitation administrative department, and the construction unit or contractor must contact the Municipal Appearance Bureau’s Debris Office for external transportation.

Pollutants generated during the project production process

  • The main production line equipment of this fertilizer production line project is advanced, mature and reliable, with high environmental indicators. During the fertilizer production process, the main pollution sources and main pollutants discharged by the project are wastewater, solid waste and noise pollution:
  1. Wastewater The wastewater generated by the project is mainly domestic sewage, and the project does not produce any toxic or harmful industrial wastewater.
  2. Solid waste The solid waste discharged by the project mainly includes waste packaging materials and employees’ daily living garbage.
  3. Noise The noise source of the project is mainly the noise generated by the electromechanical equipment in the production line and supporting facilities.

Environmental protection measures during the project construction period

Preliminary plan to control ecological impacts

  1. In order to reduce the adverse impact on the ecological environment during the construction of buildings, the construction unit shall formulate a disposal plan for the abandoned soil of the project when formulating the construction plan. The abandoned soil shall be disposed of at the specified location and the implementation of the plan shall be checked from time to time. 
  2. At the same time, the soil and water conservation plan during the foundation excavation, road construction and site leveling process shall be considered, and the temporary loose topsoil shall be properly compacted. When the slope is >25°, slope protection shall be carried out, and turf shall be planted on the permanent slope. 
  3. If toxic or hazardous waste is encountered during construction, construction should be temporarily stopped and the local environmental protection and health departments should be contacted in a timely manner. Construction can only be continued after they have taken measures. 
  4. In order to reduce the impact of project dust on the surrounding environment, it is recommended that when construction encounters continuous sunny days and windy conditions, some water should be sprinkled on the surface of the spoil to prevent dust. 
  5. Construction workers should transport away the spoil in a timely manner in accordance with the spoil disposal plan, and do not overload the soil during the transportation process. The earth-loading truck must not be spilled along the way. The soil on the wheels of the vehicle should be removed before leaving the construction site to prevent the spoil from filling the ground along the way. 
  6. Affect the cleanliness of the environment. At the same time, constructors should implement a cleaning system for the road environment in front of the construction site. Once there is spoil soil or building materials, they should be cleaned up in time.

Preliminary plan to control the impact of noise

  1. In order to reduce the impact of construction noise on the surrounding environment, construction is not allowed from 11pm to 6am the next day within an area of 200 meters from residential areas. At the same time, construction equipment and methods should be considered, and low-temperature noise should be used as much as possible. 
  2. Noisy machinery. For construction sites that must be constructed at night and may affect the residential environment, noise reduction measures should be taken for construction machinery. 
  3. At the same time, temporary sound barriers and other devices can be set up around the construction site or around residential areas to ensure the safety of residential areas. Acoustic environment quality. 
  4. Since the project construction area is an industrial area, surrounded by corporate factories and almost no residents live there, it will not have a major impact. plus Itacome is the first company that moves to the dodoma industry zone, therefore things a lot of easier this way.

Preliminary plan to control domestic waste pollution

  1. During the construction of the project, the construction workers’ meals and accommodation will be arranged in the work area. Drainage and domestic waste from these temporary accommodations should be properly disposed of, collected centrally, and sent to urban garbage disposal stations for treatment together.

Preliminary plan to control water pollution

  • For flushing wastewater during construction, it is recommended to set up a temporary wastewater sedimentation tank at the construction site to collect all types of wastewater discharged during construction. After sedimentation, the wastewater can still be reused as part of the construction water, which not only saves water resources, but also reduces the pollution to the surface water environment.

Environmental protection measures during project operation period

  • In order to maintain hygiene in the factory area and not affect the surrounding environment, the pollution sources and pollutants generated by the project must be comprehensively controlled.
  1. Domestic wastewater enters the septic tank for pretreatment. Under the action of anaerobic microorganisms, most organic matter is degraded or decomposed into small molecular substances; 
  2. Then the water volume and balanced water quality are adjusted through the regulating tank; then it enters the contact oxidation tank for aeration and biochemistry, and passes through The absorption and degradation of the biofilm attached to the filler removes most of the pollutants;
  3. The wastewater after biochemical treatment flows into the sedimentation tank to remove the exfoliated biofilm entrained in the water to achieve discharge standards. The wastewater treated by the above process can reach the first level standard in Table 4 of GB8978-96 “Integrated Wastewater Discharge Standard”.

Solid waste treatment proposal fertilizer production line

  1. Waste packaging barrels are temporarily stored at waste solid collection points and recycled by suppliers.
  2. General waste packaging materials and domestic garbage should be bagged in categories, stacked at designated points, and processed uniformly by the local environmental sanitation department.

Noise control during fertilizer plant project period

  1. In process design, low-noise equipment is preferred, and the noise of all equipment is less than 85dB ( 1 meter outside the equipment).
  2. When laying out the factory area, the main factory building where noise sources are more concentrated should be placed in the center of the factory area, and other noise sources should be placed as far away from the factory boundary as possible to reduce the impact on the external environment.
  3. The main noise equipment also adopts noise reduction measures such as sound insulation, noise reduction, and vibration reduction. Pump motors are equipped with silencers, fans are equipped with vibration isolation and noise reduction measures, power equipment uses steel concrete vibration isolation foundation, and pipelines and valve interfaces adopt slow-motion and vibration-reducing flexible joints (ports).
  4. Strengthen greening. After taking measures such as sealing the workshop, reducing foundation shock, sound insulation and noise reduction, the noise level at the factory boundary is less than 60 decibels during the day and less than 50 decibels at night. Therefore, the construction of this project will not have any adverse impact on the surrounding environment.

Environmental management and monitoring agencies

  1. Environmental protection and labor safety and sanitation work is implemented with a first-level organization and a second-level management. 
  2. The company has a full-time environmental protection and safety organization responsible for managing the environmental protection and labor safety and sanitation work of the entire factory; 
  3. The workshop has a part-time environmental protection and safety officer who is responsible for the daily work of environmental protection and safety in the workshop. 
  4. In summary, the pollution generated by the project has been properly handled and rendered harmless and recycled. Therefore, the pollution produced by the project has little impact on the surrounding areas.

Greening Plan fertilizer production line

  • Good greening not only creates a beautiful living environment, but also plays a special role in preventing pollution and protecting the environment. 
  • This project adheres to the greening principle of combining points, lines and surfaces, and tries to increase the greening rate within the project area as much as possible. 
  • It uses trees, shrubs and lawns in the form of a mixture of high, medium and low values to form a three-dimensional green space, giving full play to the protection and activity functions of the green space and improving the environment. function to keep the factory environment beautiful and tidy.

Calculate the raw material consumption for 1 ton of 15-15-15 compound fertilizer, you need to know the percentage composition of each nutrient in the fertilizer blend.

  • For a 15-15-15 SSP fertilizer, it means that the fertilizer contains 15% nitrogen (N), 15% phosphorus (P2O5), and 15% potassium (K2O).

Here’s how you can calculate the raw material consumption:

  1. Nitrogen (N):

    • Since the fertilizer contains 15% nitrogen, for 1 ton (1000 kg) of fertilizer:
      • Nitrogen required = 15% of 1000 kg = 0.15 × 1000 = 150 kg
  2. Phosphorus (P2O5):

    • Similarly, the fertilizer contains 15% phosphorus (expressed as P2O5).
    • P2O5 required = 15% of 1000 kg = 0.15 × 1000 = 150 kg
  3. Potassium (K2O):

    • The fertilizer contains 15% potassium (expressed as K2O).
    • K2O required = 15% of 1000 kg = 0.15 × 1000 = 150 kg

So, for 1 ton of 15-15-15 compound fertilizer, you would need:

  • 150 kg of nitrogen source
  • 150 kg of phosphorus source (usually as P2O5)
  • 150 kg of potassium source (usually as K2O)
  • Raw Material Preparation:
  1. Nitrogen fertilizer: Urea: 46-0-0-1 (H2O);
  2. Ammonium chloride: 23.5-0-0-5 (H2O);
  3. Phosphate fertilizer: monoammonium phosphate: 11-44-0-2 (H2O);
  4. Potash fertilizer: Potassium chloride: 0-0-60-2 (H2O);
  5. Filler: Clay: 0-0-0-6 (H2O);
  6. Finished product index: N-P-K=15-15-15 H2O≦2%
  • Calculation process:
  1. The raw material of potassium fertilizer is single. Calculate the potassium dosage first.
    15/60=0.25 servings
    The preset moisture content of the finished product is 2%, the moisture content of the potassium raw material is the same as that of the finished product, and the difference is not calculated.
  2. Phosphate fertilizer dosage:
    15/44=0.341 parts 0.341 parts Nitrogen content of monoammonium: 0.341×11=3.75
    The ammonium phosphate moisture content is 2%, which is consistent with the preset finished product moisture content, and the difference is not calculated.
  3. Nitrogen fertilizer calculation:
    Excluding monoammonium for nitrogen supply, the amount of nitrogen supplied by nitrogen fertilizer: 15-3.75=11.25
  • Because nitrogen fertilizers are available in urea and ammonium chloride, according to the granulation properties of the production materials, the optimal production formula should be a certain proportion of urea and ammonium chloride.
  1. Assuming that all nitrogen is provided by urea, the dosage of urea is: 11.25/46=0.245 copies
  2. Assuming that all nitrogen is provided by ammonium chloride, the amount of ammonium chloride is:11.25/23.5=0.479 copies
  • According to production experience, this formula design is expected to use 0.15 parts of urea, then:
  1. Urea nitrogen supply: 0.15×46=6.9
  2. The amount of ammonium chloride for nitrogen supply is: 11.25-6.9=4.35
  3. The dosage of ammonium chloride is: 4.35/23.5=0.185 parts
  4. At this time, the moisture difference is: Urea: 0.15×(1-2)%= -0.0015 parts
  5. Ammonium chloride: 0.185×(5-2)%= 0.00555 parts
  6. The amount of filler is: 1-0.591-0.185-0.15=0.074 parts
  7. The filler moisture difference is: 0.074×(5-2)%= 0.00296 parts
  8. The comprehensive moisture difference is: 0.00296+0.00555-0.0015=0.00701 parts
  9. The amount of filler after balancing the moisture content is: 0.074+0.00701=0.081 copies
  • Calculation results:
    Potassium chloride: 0.25 parts
    Ammonium chloride: 0.185 parts
    Urea: 0.15 parts
    Monoammonium phosphate: 0.341 parts
    Filler: 0.081 parts

Fertilizer project uncertainty analysis table

  • Fetilizer plant sensitivity analysis is to judge the importance of these factors on the project’s economic benefit indicators by predicting and studying the impact of changes in various uncertain factors on the project’s economic benefit indicators and the project’s risk tolerance when the factors reach critical values.
  • Assuming that a certain factor changes and other factors remain unchanged, calculate the range of changes in the project’s economic benefit indicators, and calculate the sensitivity and critical points. The critical point refers to the limit value at which uncertain factors change in an unfavorable direction. If the limit value is exceeded, the project’s economic benefit evaluation index changes the project from feasible to infeasible. 
  • According to the specific conditions of the project, a single-factor sensitivity analysis was conducted on the project’s financial internal rate of return when uncertain factors such as sales price and raw material costs changed. 
  • The analysis shows that: changes in sales price and raw material cost have the most sensitive impact on the project’s financial indicators. When the sales price and raw material cost increase or decrease by 20 % or 10 %, the financial indicators fluctuate the most , the sensitivity is greater, and the internal rate of return Increase or decrease accordingly by about 10%. It is suggested that the project party should focus on reducing raw material costs, thereby increasing product revenue, and effectively reducing the impact of unit price fluctuations on revenue.

Breakeven analysis Itracome fertilizer plant project

  • Break-even analysis Breakeven analysis is to calculate the breakeven point ( BEP) through a formula based on sales, costs, and taxes in the full-load production year. Since the fixed costs of the project are different in each year, the breakeven point of the project in the year when the design production capacity is reached during the calculation period is calculated. 
  • The project breakeven point (BEP) is as follows: BEP = annual total fixed cost / (annual sales revenue – annual variable cost – annual sales tax) × annual processing capacity = 45.18 % . 45.18 % of the designed production capacity during the calculation period , the project can maintain its capital preservation. This shows that the project has a strong ability to adapt to changes in market demand and has considerable market competitiveness.

Conclusion of comprehensive benefit evaluation

It can be seen from the economic indicators that the average annual sales revenue of the project is 8 million USD, the average annual total profit is 4 million USD, the project investment profit rate is 29.80%, and the after-tax financial internal rate of return is 18.97%. The break-even analysis shows that although the project may face risks caused by unit price fluctuations and operating costs, from the perspective of financial evaluation, the project is feasible and highly profitable.

Project risk analysis

Risk of force majeure factors

  • Force majeure refers to objective circumstances that cannot be foreseen, avoided or overcome. In this project, force majeure mainly refers to crises caused by major changes in nature. Natural risks are not subject to human will. Once a huge natural disaster that is beyond human control occurs during the implementation of the project, it will be difficult for the project to reach the designed construction level, and the progress and benefits of the project will be affected.

Tanzania local fertilizer market risk

  • In a modern society where information is changing rapidly, changes in national policies, industry environment and many other factors have increased market uncertainty. Whether you can grasp the pulse of the market, seize market opportunities and capture market share as scheduled involves greater risks. Market risks mainly include price risk, competition risk and demand risk. Any product has a certain time limit. The time from product design and trial production to commercialization and launch on the market cannot be too long. Opportunities must be seized for rapid development.

Fund raising risk

  • The investment project with raised funds will have a certain period from the beginning of the project planning to the delivery and use, and there will be many links involved. If the investment is not managed well and the budget is exceeded, it may affect the investment project’s failure to be completed as scheduled, or due to some force majeure unexpected events. Or if there is a problem in a certain link, it may also affect the implementation of the investment project as scheduled, which will inevitably affect the implementation plan of the entire project.

Risk avoidance countermeasures for force majeure factors

  • This project owner Itracome alomg with Tongli has taken strict preventive and early warning measures against possible force majeure risks: the project party will build prevention facilities and hire experts from various fields to actively carry out assessments and forecasts, strengthen prevention, and purchase corresponding risk insurance from insurance companies to ensure the basic interests of investors.
