LHY Twin-Roller Granulator

The counter-roller granulator uses the counter-roller extrusion principle to achieve direct granulation of dry powder, which can effectively increase the product's bulk density. It is widely used in the granulation of non-metallic minerals, metals, chemicals, pharmaceuticals, pesticide powders, and environmentally friendly recycled dust.


Compaction equipment






Various dry powder materials are added from the top of the equipment, enter the counter-roller after degassing and screw pre-pressing, and the material is plastically deformed and compressed into sheets under the action of the maximum squeezing force of the counter-roller. The flake materials are then crushed, sized, sieved, etc. to obtain granular products. The size of the squeezing force can be adjusted by the pressure of the hydraulic cylinder according to the needs of the granulation operation.


1. The material is forcedly compressed by mechanical pressure, without adding any wetting agent, and the purity of the product is guaranteed.
2. The technological process is short, the energy consumption is low, and the output is large.
3. Dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process.
4. The strength of the granules is high, and the increase in bulk density is more significant than other granulation methods. It is especially suitable for the occasion of increasing the accumulation ratio of products.
5. The operating flexibility is large, the adaptation range is wide, and the magnitude of the squeezing force can be adjusted by the hydraulic pressure.
