Application characteristics of counter roll granulator in NPK fertilizer production line

1. The roller press granulator has a particularly good effect on the granulation of ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc. The ball formation rate can reach 85%, without drying, and the investment is low and the effect is quick.

2. The pair-roll extruder has no drying process, granulation at room temperature, one-time molding, low investment, quick results and good economic benefits.

3. Low power, reliable operation, no three wastes discharge, stable operation, convenient maintenance, reasonable flow layout, advanced technology and low production cost.

4. The roller granulator has a wide adaptability of raw materials. It can be used for the granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, coal, metallurgy, etc., and can produce various concentrations and types (including organic fertilizer, Inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) compound fertilizer.

The working principle of the roller press granulator: This series of organic fertilizer machine is an extrusion sliding model. Its working principle is that the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and passed through the split gear and the passive The axes are synchronized and work in opposite directions. The materials are added from the hopper, formed by rollers, demoulded and pelletized, and passed through a pair of chains, transferred to the crushing sieve workshop, under the sieve and separated the finished product particles (balls), and then returned to mix with the new materials. Perform granulation. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.
