Advantages of roller extrusion granulator

The extrusion form of the double-roller extrusion granulator has two types: front discharge and side discharge. The prepared material is feeded from the top of the double-roller extrusion granulator, and there is a vertical screw in the groove. Through the rotation of the screw rod, the material is forcibly sent to the bottom of the double rollers granulating machine for extrusion, and the two rollers rotate relative to each other, so that the sent material becomes cake-shaped, and the cake-shaped strips enter the shredder and are broken by the rotating knife row. The crushed material enters the granulator and passes through the rolling knife row to make the particles and part of the powdery material enter the vibrating screen for screening. Qualified pellets are sent to the outside through. The sifted powder material is sent back to the raw material bin for secondary rolling, and the size of the extrusion force can be controlled by the hydraulic system according to the needs of granulation. By changing the shape of the groove on the roller surface, you can produce fertilizer pellets with sheets, strips, and oblate sphere shapes. Click here for more information.

1. The roller extrusion pelletizer is carefully manufactured with strong anti-corrosion and wear-resistant materials, which has the advantages of beautiful appearance, simple operation, low energy consumption, long life and high granulation rate.
⒉ The roller extrusion granulator adopts no drying process, normal temperature granulation, one-time molding, less investment, quick effect and good economic benefit. Small power, reliable operation, no three wastes discharge, stable operation, convenient maintenance, reasonable process layout and low production cost. The raw materials have wide applicability and can be used for 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,  etc.) compound fertilizer.

3. The equipment of the roller extrusion granulation is relatively small, occupies a small area and is relatively compact. The price is also cheaper. Suitable for small batches of organic fertilizer granules.
4. The disadvantage of the roller extrusion granulator is that the output is relatively small, and it is not suitable for the granule processing of large-scale organic fertilizer production lines. Since it is a dry granulator, it has requirements on the moisture of the material.
It can be seen from the above that the double-roller granulator is compact, flexible, and occupies a small area. Moisture treatment of high-humidity materials is required before granulation, which is suitable for the processing of organic fertilizer granules with small production capacity.
