Fertilizer Machine Manufacturer Introduces How to Produce Compound Fertilizer

Posted by Fertilizer Machine on November 14th, 2019

The common granulation processes of compound fertilizer include tower granulation, rotary drum granulation (NPK fertilizer production line), spray granulation and so on. As fertilizer machine manufacturer, let's introduce these production processes from the perspective of fertilizer production.

1. High tower granulation process is mainly used for the production of high concentration nitro compound fertilizer. It can directly use concentrated ammonium nitrate solution, eliminating the links of spraying granulation, and granular compound fertilizer eliminates the process of crushing operation. At the same time, the compound fertilizer granules produced by the high tower granulation process are very uniform, the qualified rate is very high, the quality is good, easy to dissolve, and the caking phenomenon will not occur.

2. Rotary drum granulator has little restriction on compound fertilizer formulation, high production yield, low investment and construction speed. It is favored by investors of small and medium-sized compound fertilizer plants and widely used in compound fertilizer production. The complete drum granulation process is a NPK compound fertilizer production line, which includes fertilizer granulator, automatic batching system, mixer, crusher, drum dryer, drum cooler, coating machine, packaging machine and other equipment.

3. The spray granulation process adopts the slurry method. The slurry is sprayed into the equipment by heating and pumping, so that the moisture in the slurry is vaporized and separated, and the retained solid forms a granular compound fertilizer. This kind of process is widely used in large-scale compound fertilizer production. Its advantages are that it can be used to produce NPK compound fertilizer, and can also be used to produce ammonium phosphate compound fertilizer. At the same time, it has less energy consumption, large production scale and low production cost. The quality and strength of the products are very good.

We are fertilizer machine manufacturing enterprise with many years of experience. The drum granulation NPK compound fertilizer production line is our main equipment product. Among the equipment sold, it is highly praised by many fertilizer factories internationally.
