Extrusion granulator equipment for NPK compound fertilizer production process

The double roller extrusion granulator has low investment and good economic benefits. The NPK production line has a compact layout, scientific and reasonable, and advanced technology. It is suitable for the granulation of various raw materials such as compound fertilizer, medicine, chemical industry, and feed, with high granulation rate. Various concentrations and types of NPK compound fertilizers can be produced.

Working principle of roller extrusion granulator

The roller granulator belongs to extrusion sliding model. Its working principle is that the belt and pulley are driven by the motor, which are transmitted to the driving shaft through the reducer, and are synchronized with the passive shaft through the split gear. The material is added from the feed hopper, extruded by roller, demoulded and pelletized, and then transported to the crushing screen working room through a pair of chain, screened and separated the finished particles (pellets), and then the returned materials are mixed with the new materials, and then pelletized. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.
