Sand works first by machine materials fall within the upper portion of the vertical high-speed rotation of the impeller, and then under the action of high-speed centrifugal force, and the other part of the umbrella in the form of diversion around the impeller material impact stone crusher occurred after the impeller and a strong vortex formed between the casing in each other again or repeated impact and friction, crushed. Sand discharge from the lower part of the final discharge port, and then reach the desired finished size is controlled by the screening equipment. The impeller is an important part of the Sand, is also a part of the most vulnerable, because the material is dispensed at the completion of the impeller in the launch, if the improper operation of a stone crusher's portfolio, it is likely to cause material worn impeller, so we specifically work and operations should be careful to avoid because inadvertently, accidentally causing a series of accidents. We know that the impeller shaft mounted on the upper end of the spindle assembly head pass button from the stone crusher models with tapered sleeves and key connection, high-speed rotation, while the central portion of the material from the impeller feeder feeding tube into the center of the impeller. From the center of the impeller cone fabric homogeneous distribution of the material flow to the impeller of the respective transmit path, the transmit channel outlet mounting block special wear-resistant material, the material of the impeller can be changed to accelerate to a constant speed out of the projectile impact to the vortex move the stone crushing cavity lining materials Sand series classification, performed strongly since crushed between the impeller mounted on a cone hat and wear blocks, indecent channel plate, thereby protecting it from wear and tear. When the device is stopped before it should be noted that: before stopping the discharge device first stop feeding, feeding should continue uniform, strict compliance with the requirements of the specifications of materials, otherwise the material is also very easy to wear because of the impeller.
