Production process of compound fertilizer by roller extrusion granulation
Granulation is an important link in the production process of organic fertilizers and compound fertilizers. The roller extrusion granulator equipment is common fertilizer granulator machine with features such as advanced technology, reasonable design, compact structure, novelty and practicality, low energy consumption. It can be matched with corresponding equipment to form a small production line.

One. Product overview:
The double roller granulator needs to be dried, produced at room temperature, and the product is formed by rolling to make the product quality meet the technical index requirements of compound fertilizer. It is used to produce high, medium and low concentration special compound fertilizer and compound fertilizer for various crops and renewal products for energy saving and consumption reduction in fertilizer industry. At the same time, it is suitable for the granulation of various raw materials such as chemical feed.

Two. The main features of the product:

1. Double-roll extrusion granulator Drying process, granulation at room temperature, secondary molding, low investment, quick results, and good economic benefits.

2. The compound fertilizer counter-roller extrusion granulator has low power, reliable operation, three wastes discharge, stable operation, convenient maintenance, reasonable flow layout, advanced technology, and low production cost.

3. The roller extrusion granulator has a wide applicability 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, organic fertilizer, biological fertilizer, magnetic fertilizer, etc.) compound fertilizer.

4. The twin-roll extrusion granulator, especially the granulation of rare earth, ammonium bicarbonate, and ammonium sulfate compound fertilizers, fills the gap and ranks at the leading level. It is a promotion project of national environmental protection applicable technologies.

Three. The working principle of the roller granulator machine for fertilizer:
This series of extrusion granulator 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 synchronized with the driven shaft through the split gear, and work in opposite directions. The material is added from the hopper, formed by rollers, demoulded and pelletized, and passed through the auxiliary chain, transferred to the crushing screen studio, under the sieve and separated the finished product particles (balls), and then the returned material is mixed with the new material before proceeding. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.
