Introduction of Roller Compact Granulator Machine Fertilizer

Compound Fertilizer Double Roller Granulator is the key equipment for compound fertilizer granulation. It uses squeezing principle to form fertilizer particles with diameters of 3.5-10mm in one time. Double Roller Press Granulator has higher granulating ratio of over 95%. With no drying technology, materials will be pressed into ball shape to meet the requirements of compound fertilizer production. The shape and size of the ball socket on the roller shell can be customized by customer.

Feature of Fertilizer Roller Compactor Granulator

1.Easy operation and maintenance, no need installation for fertilizer roller granualtor machine.
2.Low energy consumption and no waste water or gas emission
3.Dry Type Granulation Machine works in dry granulation process, normal temperature granulating, one-step forming.
4.Press rollers adopt new metal which is resistant to corrosion, wear and impact.
5.Self spare parts manufacturing


Advantage of Roller Compact Granulator Fertilizer

1.Reasonable structure, NPK fertilizer granulator machine will be tested before transporting and roller will be polished in perfect using
2.High granulating ratio, higher than 95%
3.Wide application scope: no only for NPK fertilizer production, but for cat litter working
4.High granulating ratio, higher than 95%
5.No drying need in Dry Granulation Machine , simple working make big benefits
6.Environmental working, low energy consumption and no waste emission

Working Principle of Double Roller Granulator Fertilizer

This series of roller compactor granulator is extruded model, and its working principle is: Electromotor drive the belt and pulley, then it is transmitted to the driving shaft by the speed reducer, and by synchronizing the open gear with the passive shaft, achieving the working in the same direction. Material is added from the hopper, after the roll extrusion forming, demoulding pelletizing; and through a chain, the balls are transferred to the broken screen studio, sieving and isolate the finished products (the balls), then return to mix with new materials and granulate again.
