The machine is made up of main engine, auxiliary engine and electrical control box with the capabilities of winnowing, non-sieve or mesh, even granule size, continuous operation, etc. The machine reaches the international advanced lever and is widely used for material grinding in pharmaceutics, chemical, foodstuff industries, etc.
2. Working principle:
Raw material is delivered to the grinding chamber via hopper by spiral feeder, and is cut and sheared by the high speed cutters. Then the material is moved into the whirlwind separator and the sack dust catcher by the negative pressure sucking method. The ejection meets the product requirement.
◆ 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 conveying .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 not 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 pulverize 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.
