The double roller granulator is a dry granulator. The granules formed are oblate spherical. The granule size is determined by the die size and can be customized. LANE can customize a dedicated double roller granulator for you to meet any of your needs.

Prepare the raw materials required for the roller granulator (such as powdered organic fertilizer, compound fertilizer, graphite, etc.) and feed them into the roller granulator through the feed hopper. Through the rotation of the screw rod, the material is forced to be extruded between the two rollers at the bottom.
After the material reaches the bottom, the two rollers rotate relative to each other and use the mold shell to extrude the material, and the material becomes a cake or strip under strong pressure.
Then, the extruded material enters the granulator and is broken into loose particles by the rotating knife row. Then enter the granulator and further organize it by the rolling knife row to make the shape of the particles more regular.
The processed particles enter the rotary vibrating screen for screening, and the qualified particles are screened out, and the screened powdered materials are sent back to the raw material bin for secondary rolling.
The extrusion force of the roller granulator can be controlled by the hydraulic system to meet the granulation needs of different materials. At the same time, by changing the groove form of the roller surface, different shapes of materials such as flakes, strips, and oblate balls can be obtained.

Low cost, wide range of materials
During the granulation process, there is no need to add water, and after the granulation is completed, there is no need to dry the particles, greatly reducing the drying cost. Applicable materials include powdered organic fertilizer, composite fertilizer, graphite, mineral powder, industrial salt, snow melting agent, fragrance beads, etc. Some coarse fiber materials can also be used.
Durable and long-lasting
The double roller granulator skin can be customized, and the material is high chromium 13/304 stainless steel. After surface immersion treatment, the anti-corrosion and wear-resistant effect is quite good.
Flexible configuration
Dispersal devices can be added at the inlet and outlet to prevent raw materials and finished products from sticking together. A dispersal device can be added below the drum to prevent materials from sticking to the drum.
