Working principle of dry roller press:

The binder-less dry roller granulation technology is a very competitive technology. In general, the particles are not formed by the solid bridge between the particles, but by the strength of the particles formed by the force between the molecules.

The powder is continuously fed into the roller press from the hopper, and the hydraulic roller gives pressure to the moving roller. The powder starts to contact the roller and then is driven by the friction of the roller surface. The powder is added between the two rollers rotating in the opposite direction. Press and squeeze. Under the squeezing force of the roller, the material is plastically deformed and compressed into sheets or strips. The flakes or strips are then crushed, sieved, re-sifted, packaged, and dedusted to obtain clean granular products.

The pressing force of the roller can be adjusted by the pressure of the hydraulic cylinder according to the requirements of the granulation operation. Different pressure settings can get finished particles with different strength.

Features of dry roller granulator :

1. Dry compaction, without adding any wetting agent, subsequent drying is not required, the material is forced to compression molding by mechanical pressure, and product purity is guaranteed.

1. The process flow is short, the energy consumption is low, and the granulation system is closed-loop operation to achieve continuous production.
2. The advanced power system adopts dual-shaft output reducer and drum gear coupling, which effectively protects the rollers and main bearings from damage and improves the transmission efficiency.
3. The roller is made of high-quality alloy steel forged, which greatly improves the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, making the equipment work more stable and durable.
4. The equipment is equipped with a hydraulic system. By adjusting the squeezing force, the strength of the granules and the accumulation ratio are improved more than other granulation methods.
