The process and supporting equipment of the compound microbial fertilizer production line are as follows:

Process of compound microbial fertilizer production line:

Raw material ingredients: Prepare urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, superphosphate), potassium chloride (potassium sulfate) and other raw materials in a certain proportion. This ratio is determined based on market demand and soil testing results in various regions.

Raw material mixing: Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles.

Raw material granulation: The evenly stirred raw materials are fed into a granulator for granulation. Here, you can choose between a drum granulator or an extrusion granulator.

Particle drying: Feed the fertilizer granules made by the granulator into the dryer to dry the moisture contained in the granules, increase their strength, and facilitate storage.

Particle cooling: The temperature of the dried fertilizer particles is too high and prone to clumping, so cooling is necessary for easy bagging, storage, and transportation.

Particle classification: The cooled particles are classified, and the unqualified particles are crushed and re granulated to screen out the qualified products.

Finished product coating: Coating qualified products to increase the brightness and roundness of the particles.

Supporting equipment for compound microbial fertilizer production line:

Ingredients equipment: used to mix various raw materials according to the set proportion.

Mixer: used to evenly mix the prepared raw materials.

Granulator: It can be a drum granulator or an extrusion granulator, used to make uniformly stirred raw materials into particles.

Drying machine: used to dry the granulated particles and remove excess moisture.

Cooling machine: used to cool the dried particles and prevent clumping.

Grading screen: used to classify cooled particles and screen out unqualified particles.

Coating machine: used for coating qualified products, increasing the brightness and roundness of particles.

Automatic packaging machine: used to automatically package wrapped products for easy storage and transportation.

The above is the production process and supporting equipment of composite microbial fertilizer. It should be noted that the specific equipment configuration may vary due to factors such as production process, raw material characteristics, and production scale. Therefore, in the actual production process, it is necessary to choose and adjust according to specific circumstances.
