It has advanced technology, reasonable design, compact structure, novel and practical, and low energy consumption. It can form a small production line with the corresponding equipment. It can form a certain capacity of continuous and mechanized production. Adopting a healthy formula, no need for drying, normal temperature production, product rolling forming, and making product quality meet the technical requirements of compound fertilizer, is used for the production of various crops with high, medium, and low concentration of special compound fertilizer.
The series of roll granulation is an extrusion model, its working principle is the belt and pulley driven by electric motors, to the driving shaft to pass through the reducer, and synchronization of the gear and the driven shaft opposite the work. Material from the hopper to feed, after the roll extrusion molding making into a ball shape, then to the broken screen to finish the separation, finally get the even oval shape granules.

Three-layer double roller press granulator
Using multi-stage extrusion and molding, better granulation effects can be achieved, and particle size and density control are more precise.
