Due to the role of centrifugal force when rotating, grinding roller swing outward, pressed against the grinding ring, so that shovel shovel material from the grinding roller and grinding ring, ultrafine mill to achieve the purpose of crushing materials. And then collected by the wind to the finished product.

The wind selection process is as follows: After the material is ground, the fan blows the wind into the main shell, blows the powder, is sorted by the analyzer placed above the grinding chamber, the fineness of the material is falling into the grinding chamber, Fineness in line with the specifications of the wind into the whirlwind collector, collected after the discharge through the powder mouth, that is finished.

The airflow is returned to the fan by the return air duct at the top of the large cyclone collector. The air duct is circulated and flows in the negative pressure state. The increase of the air volume of the circulating air duct is exhausted through the exhaust pipe in the middle of the fan and the host, into the small cyclone collector, and finally the purification process is carried out.
