The double roller press granulator is an improved product that absorbs the new technology of the international organic fertilizer granulator machine. The machine is equipped with a feeding system that is connected with a pre-continuous feeder with a machine touch device and a forced feeding screw feeding hopper, which ensures the continuity, adequacy and uniformity of the feeding, which is an important step. The paired rolls are engraved with evenly distributed arc grooves, which is beneficial for the material to bite into the rolls, causing the arc groove to seal the cavity (belt) during operation, which is also beneficial for the compaction of the material, reducing the forming pressure of the mechanism and the load of the main engine, and improving the manufacturing process. 
The key structure of the roller granulator is the roller and the mold. The belt and the pulley are driven by the motor, which is transmitted to the driving shaft through the reducer, and works synchronously with the driven shaft through the split gear. The material is fed from the feeding hopper, extruded by rollers, demolded into balls, driven by a pair of chains, and sent to the crushing screen.
The roller extrusion granulator is the key equipment for fertilizer granulation. It has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and is matched with corresponding equipment to form a small production line, which can form a certain continuous production and mechanization. The ability of production, non-drying, room temperature production, product rolling molding, product quality meets the technical requirements of fertilizer, npk fertilizer granulator is a new product for energy saving and consumption reduction in high, medium and low concentration special organic fertilizer and compound fertilizer industry.
The complete set of equipment has a compact layout, scientific and reasonable layout, advanced technology, energy saving and consumption reduction, no three wastes discharge, stable operation, reliable operation, convenient maintenance, and wide adaptability of raw materials. High granulation rate.
