The material enters the grinding chamber via the screw feeder and then sheared and broken by the fast-rotating knives . The power passes the guide ring and enters the classification chamber. As the classification wheel is in revolution, both the air force and centrifugal force act on the powder.
As the particles whose diameters are greater than the critical diameter (diameter of the classification particles) have a great mass, they are thrown back into the grinding chamber to be ground again, while the particles whose diameters are smaller than the critical diameter enter the cyclone separator and bag filter via the material exit pipe be means of negative pressure wind conveyance.The discharge material meets the requirement for the product.
1. In the machine chamber, there is the leaf structure. When operation, the air in the grinding chamber is blown out by the rotary leaves taking out the heat. Therefore, there is no much heat in the chamber to ensure the characteristic of the material.
2. When operation, the strong air flow can expel the material out. So it can pulverized the heat sensitive and sticky material with good effect.
3. For the good performance on the heat, it can be the substitute of universal crusher.
4. Expect the pull force of the fan, the air flow in the grinding chamber blows the fine powder out (the fineness of the powder is adjustable through the sieves). Thus, it can increase the capacity of the machine.
