Multi-layer roller extrusion granulator is a new generation of organic fertilizer extrusion granulation equipment developed by our company. It can be used to extrude graphite powder, make carbon enhancer, and artificial diamond. Organic fertilizer multi-layer double-roll extrusion granulator has low investment, quick effect, good economic benefits, compact layout of the whole set of equipment, scientific and reasonable, advanced technology, novel and practical, low energy consumption.

The Multi-layer roller extrusion granulator is driven by a motor belt and pulley, which is transmitted to the driving shaft through a reducer and works synchronously with the driven shaft through a split gear. After die extrusion molding, demolding granulation, crushing and separation, uniform granulation is achieved. The extrusion die is carefully forged with excellent corrosion-resistant and wear-resistant materials. The shape and size of the ball socket on the roller skin can be determined according to user needs. The double-roller extrusion granulator has a wide range of choices. The ball pressing shapes are pillow-shaped, semi-circular particle shape, rod shape, tablet pill shape, walnut shape, flat ball shape and square strip shape. The double-roller extrusion granulator is produced by a non-drying normal temperature process and is formed in one time.

The new Multi-layer roller extrusion granulator is mainly used for the production of high, medium and low concentration compound fertilizers for various crops, graphite powder, especially the granulation of rare earth, potash fertilizer, ammonium carbonate and other series of compound fertilizers.

1. A stirring device is installed at the feed inlet to effectively ensure uniform feeding.
2. The main frame of the box is equipped with a refueling self-cleaning device to prevent textile materials from sticking to the roller skin.
3. The roller skin gap adjustment adopts step-by-step gear adjustment to ensure uniform gap and easy operation.
4. The roller skin is aligned by the gear internal spline adjustment to ensure neat alignment and no misalignment.
5. The balling rate is as high as 95% and the particle size is good.
6. The finished particles do not need secondary drying, are produced at room temperature, and have low moisture content.
6. One-time extrusion molding, high production efficiency.
7. Product particles are available in a variety of shapes and sizes.
