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 fertilizer production plant equipment introduction in detail:

1. 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:

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;
Sealed treatment, 99% deodorization, no pollution;

Aerobic bacteria can survive and reproduce at -25℃-80℃, and the beneficial bacteria formed can kill harmful bacteria in the raw materials.
Using tongli’s latest technology, the original 20-hour fermentation process can be shortened to 9 hours.

2. 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:

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%.
Secondly, the crushing and preparation of raw materials can be carried out even when the production line is not running.
Enough raw materials.
The forklift silo can reduce workers and reduce production costs.

3. 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 advantages of wet material bulk crusher:

The structure of organic fertilizer bulk crusher:

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.
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.
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.
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.
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:

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;
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.
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.

4. 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.

5. 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

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.
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.
Granules are directly processed from pure organic matter, and the characteristics of organic fertilizer raw materials are embedded and enlarged under certain effects.
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.
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.
Specialty for granulating organic fermented fertilizer, the particles are irregular pellets.
The qualified granulation rate of this machine is as high as 90%, and it is suitable for a variety of different formulas.
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.
This machine is most suitable for direct granulation of organic fertilizer after fermentation, saving the drying process and greatly reducing manufacturing costs.

6. 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. Note here that all dryers in the compound fertilizer industry are driven by large and small gears. If someone says it is a center drive, then It shows that he is bull shitting. There is only one type of steam pipe dryer, which is a center drive, but only tongli can produce that type in China, and it is used to dry the chemical raw material melamine. Back to our topic,

Dryer main body shell part:

The barrel of the dryer is also a very critical component. Tongli has the best processing equipment and processing personnel in the country, as well as the most professional design team. Tongli’s lifting plate layout has its own patent, and Tongli’s barrel processing technology It is also different from other manufacturers. The thickness of the cylinder version is at least 1.5 times that of other manufacturers. It is also thickened under the riding ring and girth gear, and is welded with the entire rear steel plate. No splicing is required. Some small factories Use splicing because they lack technical skills or cut corners. More importantly Tongli’s quality team is No.1 in the fertilizer equipment industry, we do PT, MT, UT, we manufacturer for BASF and Thyssenkrupp so you know the quality level.

7. Cow dung organic fertilizer rotary cooling machine/cooler

The organic cow dung manure rotary cooling machine accelerates the air flow inside the rotating cylinder through the suction of the induced draft fan (used in conjunction with the equipment), and continuously turns the material up through the lifting plate installed on the rotating wall, thereby achieving the purpose of cooling.
This machine is mainly used for the production of organic fertilizers, compound fertilizers, and compound fertilizers. It cools granular fertilizers at a certain temperature. The rotary cooler is used in conjunction with the dryer, which can greatly increase the cooling speed, reduce labor intensity, increase output, and further remove part of the water. and reduce the grain temperature of compound fertilizer.
The rotary cooler can also be used to cool other powdery and granular materials. The design has compact structure, high cooling efficiency, reliable performance and strong adaptability.

Chicken manure organic fertilizer rotary cooling manual operation

Before starting the machine, check whether there is any debris in the machine.
Check whether all parts of the machine are normal.
After starting the machine, check whether the rotation direction is correct. If it rotates in the opposite direction, stop the machine immediately and make adjustments. Start production after confirming that the rotation is stable and there is no noise or friction.
It is strictly forbidden to allow iron, stones, wood and other debris to enter the machine to prevent damage to the equipment.
Gear oil must be added to the reducer before it can be used for production. The gear oil must be replaced every four months.
Gears, ring gears, rolling belts, supporting wheels, etc. all need to be added with yellow dry oil.
Before shutting down, the internal materials must be discharged cleanly and then shut down to prevent the materials from sticking to the cylinder body and prepare for the next start, which will facilitate the next team production.

8. Rotary drum coating machine cow dung organic fertilizer production

The complete set of equipment of the rotary coating machine consists of a screw conveyor, a mixing tank, an oil pump, a host machine, etc. It consists of a powder coating or liquid coating process, and is controlled by a Siemens PLC. It can effectively prevent the agglomeration of compound fertilizers. The main unit is lined with polypropylene or acid-resistant stainless steel.
This equipment has a special anti-corrosion design on the internal structure according to the process requirements. It is an effective special equipment for compound fertilizer.
The working principle of the rotary coating machine is: the main motor drives the reducer. This transmission method is the most reliable and advanced, but it is also the most expensive. Small manufacturers will use drive belts and pulleys for transmission, but this is cheap and unreliable. The motor is transmitted to the driving shaft through the reducer, and the small gear mounted on the shaft engages with the large ring gear fixed on the body and works in opposite directions. Materials are added from the feed end and pass through the inside of the cylinder. Under the suction of the induced draft fan (used in conjunction with this machine), the air flow inside the cylinder is accelerated to achieve cooling and dust removal effects.

Rotary coater structure for chicken manure organic matter

Even tho the structure of the

Rotating part: The entire rotating part of the coater machine body is supported by the support roller and is subject to large forces. Therefore, the shell part of this machine is welded with medium carbon steel plates and channel steel, and has passed strict quality control and special process requirements, and has achieved the purpose of this machine.
In addition, the more important thing is the riding ring fixed on the frame. Considering that it will cause great friction with the riding ring of the machine body, our factory specially chooses anti-corrosion and wear-resistant materials, which greatly improves the service life of the machine.
The support roller frame casting integrated technology is also used. In addition, there are lifting hooks at the four corners of the wheel frame to facilitate loading, unloading and transportation.
Transmission part: The transmission part of the entire granulator is particularly important, and the work of the entire machine is based on this. The transmission frames are all welded from channel steel and have passed strict quality requirements. The main motor and reducer installed on the transmission frame are all selected products with reliable quality. The motor drives the pulley, V-belt, and reducer to the main shaft to make the machine body work. The transmission reducer and the working part of the main shaft use a nylon pin connector to engage and transmit the drive.
Girth gear: fixed on the body, meshing with the transmission pinion, driving the body in opposite directions. It uses high-tech wear-resistant materials to extend the service life of the machine.
Riding ring: fixed on both sides of the machine body to support the entire machine body.
Body shell: The most important part of the entire coating machine is the body part, which is welded with medium carbon steel plates and undergoes strict quality control and specific process requirements to achieve the purpose of the machine.

9. 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.

Rotary trommel/screening machine organic chicken manure cow dung

Frame part: The frame of this machine is welded with high-quality carbon steel plates and channel steel, and has passed
Strict product qualification certification and specific process requirements have achieved the purpose of this machine.
of;
Screen part: The screen of tongli trommel screen is made of all SS304 stainless steel, and the quality is absolutely reliable. And the diameter of the SS304 steel wire of the screen is 2.5mm, so there is no problem for people to stand on it.
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.
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;

10. Tongli ZJ series fertilizer chainmill aka chain crusher

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.
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.

11. 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:

Fully automatic: which means the bagging process is done by robot which is a expensive bagging machine. Tongli also provide this type of fully-automatic packaging system. Our last case is in tanzania.
Semi-automatic: which the bagging process is done by manual, and need a worker to put the bag to the stitching machine.

So in conclusion: these two type of packaging solution are all automatic, the difference is the bagging process is whether done by manual or by hand. So we attached a video in here and you will understand what is the difference.

Customizable Options: Depending on specific requirements, conveyors may be customized with features such as incline or decline sections, side skirts, and discharge chutes to optimize performance for the intended application.

Belt Structure:

The belt structure is often reinforced with layers of fabric or steel cords to provide strength and prevent stretching or sagging, especially when conveying heavy loads.

Troughed Design:

Troughed Design: Fertilizer belt conveyors usually feature a troughed design, where the belt is supported along its length by idler rollers, forming a trough shape. This helps contain the material being conveyed and prevents spillage

Belt drive systems:

They are typically powered by electric motors, which may be positioned at various points along the conveyor length depending on the design and layout of the facility.

Corrosion Resistance:

Since fertilizers can be corrosive, especially when they contain chemicals or acids, conveyor components are often made of corrosion-resistant materials like stainless steel or coated with protective layers.

Dust emission control:

This is a very important aspect, our tongli belt conveyor take into consideration that the dust in the workshop needs to be controlled to the minimum, therefore we have dust cover on all the belt conveyor as well as the feeding part so that the dust can be collected and send back to the system for re-processing. This is a big feature becasue owner can save tons of money just based on how much of the dust can be collected and reused.

Variable Widths and Lengths:

Fertilizer belt conveyors come in various widths and lengths to suit different applications and space constraints within the facility.

Belt conveyor system safety Features:

Conveyors are equipped with safety features such as emergency stop buttons, guards, and sensors to prevent accidents and ensure safe operation. So the worker can stop the conveyor anytime. Also there are interlock system in the PLC that if one point of the fertilizer plant stops the belt conveyor will stop also, all for the safety of the workshop.

14. Power transformer dry type for cow dung organic 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:

Good environmental performance. Dry-type transformers do not require the use of insulating oil and therefore do not cause pollution to the environment.
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.
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.
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.
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.
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.
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.
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.

Conclusion:

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.
