The double roller press granulator is a molding machine that can make materials into specific shapes. The double roll extruding granulator has a particularly good granulating effect on ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc. The granulation rate can reach 85%, without drying, with less investment and quick effect.
1. The double roller press granulator has no drying process, granulating at room temperature, one-time forming, low investment and good economic benefits.
2. Small power, reliable operation, no discharge of three wastes, stable operation, convenient maintenance, reasonable process layout, advanced technology and low production cost.
3. The invention has wide adaptability to raw materials and can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, coal, metallurgy, etc. It can also produce various concentrations and types of compound fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.).
4. Double roll extruding granulator, especially rare earth, ammonium bicarbonate and ammonium sulfate compound fertilizer.
Working principle of the double roller press granulator: the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and work in reverse synchronization with the driven shaft through the split gear. The material is added from the feed hopper, demoulded and granulated by double roll extrusion, and then transported to the crushing chamber through a pair of chains for crushing. The finished granules (balls) are separated under the screen, and the returned materials are mixed with new raw materials for granulation. With the continuous rotation of the motor and the continuous entry of materials, mass production is realized.
