Best Fertilizer Granulator

Fertilizer granulator is a kind of equipment to process powder or granular fertilizer into granular fertilizer with uniform size and regular shape. Through granulation, the fertilizer can improve liquidity, reduce dust, facilitate transportation and application, and also improve the physical properties of the fertilizer and increase the utilization rate of the fertilizer.

Why do we need granulation?

• Improve fluidity: Granular fertilizers have better fluidity than powdered fertilizers and are less likely to clump, making them easier to transport and apply.
• Reduce dust: Granulation reduces dust, improves the working environment and protects the health of the operators.
• Improved physical properties: Granular fertilizers have better physical properties, such as porosity, surface area, etc., which are conducive to the release and absorption of nutrients.
• Improve the utilization rate: Granular fertilizer can reduce the loss of fertilizer, improve the utilization rate of fertilizer.

Common process of fertilizer granulation

The common processes of fertilizer granulation mainly include the following methods:

1. dry granulation and wet granulation

Dry granulation

Dry granulation does not use liquid solutions and usually employs extrusion granulation technology. In this process, the raw materials are polymerized into granules under high pressure without drying or cooling, which is suitable for small and medium-sized fertilizer plants with low investment. Pellets from dry pelletizing are usually flat, with high curability, but with coarse particles.

Wet granulation

Wet granulation requires the addition of water or binder, and commonly used equipment includes rotary drum granulators and sprayers. This method produces granules with high moisture content and therefore requires a subsequent drying and cooling process. Wet granulation is characterized by uniform particles and is suitable for the production of a wide range of compound fertilizers, such as DAP (Diammonium Phosphate) and urea.

Characteristics	Dry Granulation	Wet Granulation
Principle of Process	No liquid is added, relying on compression molding	Water or binder is added to form granules
Advantages	No need for drying, saving time and cost Suitable for heat-sensitive and easily decomposable materials High production efficiency, low energy consumption Good granule flowability, convenient for subsequent processing	Uniform granules with good appearance Uniform nutrient release, better fertilizer effect Wide application range, can handle various raw materials Suitable for large-scale production
Disadvantages	High requirements for materials, need fineness Relatively low granule strength Not suitable for some sticky materials	Requires subsequent drying, increasing production costs May cause material adhesion, affecting flowability Complex production process, high equipment requirements

2. Specific granulation processes

Spray slurry granulation

Spray slurry granulation is the nitrogen and phosphorus slurry mixed with other raw materials, through the spray method of granulation, nutrient uniformity, suitable for the production of high-efficiency compound fertilizer. The advantage of this process is that the nutrients are released evenly, and the fertilizer effect is better.

Tower granulation

Tower granulation process is to melt urea and other raw materials mixed reaction, the production of compound fertilizer nutrient distribution is uniform, suitable for rapid dissolution, commonly used in fertilizer. The disadvantage of this process is that the nitrogen content is high, the phosphorus content is limited, and may lead to the content of diurea exceeds the standard.

Granulation drum

Granulation drum is a mixture of nitrogen fertilizer, phosphate fertilizer and potash fertilizer to form particles in the drum. This method is simple, but the nutrient mixture is not uniform enough, the water solubility rate and utilization rate is low, and it is easy to be lost.

Dry powder physical granulation method

This method is through the selection of dry powder fertilizer raw materials and binder, in the granulator heating and water to form particles, suitable for deep processing BB fertilizer production, granulation conditions need to be controlled in a specific range of temperature and water content.

Types of Fertilizer Granulator

Fertilizer granulator is one of the key equipments in fertilizer production process. It can make powdery or granular raw materials into spherical or columnar particles. Several common types of fertilizer granulators include.

1. disk type granulator

Disc granulator is one of the most important granulation equipment in the fertilizer production line. It has the following advantages.

• The pan adopts circular arc structure, and the output of compound fertilizer reaches 93%.
• The pan surface is made of strong iron material, simple structure, high yield of fertilizer granule and convenient maintenance.
• Stable and reliable operation, low noise
• Suitable for organic fertilizer and compound fertilizer production line

2. Double-die extruder granulator

Double-die extruding granulator combines many advanced extrusion technologies together and is one of the most commonly used equipment in organic fertilizer production. It can produce high quality fertilizer granules.

3. Rotary drum granulator

Rotary drum granulator is mainly used in compound fertilizer production line, with high output of fertilizer granules, suitable for large-scale fertilizer production requirements.

4. Flat Die Extruding Pelletizer

Flat film pelletizer can produce granular feed, organic fertilizers, can produce cylindrical pellets, can also be connected to a variety of molds to adapt to the pelletizing needs of different materials.

5. Roller extrusion granulator

Roller extrusion granulator is suitable for dry materials with moisture content less than 8%, which is used in compound fertilizer production line to produce nitrogen, phosphorus and potassium compound fertilizer and urea.

6. New organic fertilizer special granulator

New organic fertilizer special granulator is specially designed for organic fertilizer material characteristics and a kind of granulation equipment. It overcomes the traditional granulator in the treatment of organic materials, there are many problems, such as serious bonding, easy to clog.

In summary, different types of granulators have their own characteristics, suitable for different fertilizer production needs. Selection should be combined with the actual situation for selection.
