1. Reasonably reduce the humidity of the material
    If the water content in the material is large, the material is easy to adhere to the crushing cavity, and it is easy to be blocked during the feeding process, which reduces the production capacity of the impact crusher. Therefore, the material with large moisture content can be dried or dried in advance to reduce the humidity of the material reasonably.
    2. Pre-screening materials in advance
    The materials are pre-screened in advance, and the bulk and powdery materials are screened out for processing, so that the materials entering the crushing cavity more meet the crushing design requirements of the impact crushing, which is beneficial to increase the productivity of the impact crushing.
    3. Reasonably increase the power of the main motor
    Within the range of rated motor power, the er the power of the main motor, the higher the production efficiency of counterattack and the higher the productivity. Therefore, within the allowable range, the main motor power can be increased to increase the production capacity of counterattack.     4. Properly increase the speed of the rotor
    With the increase of the rotor speed, the production capacity and crushing ratio of the impact crusher will increase significantly, and the product particle size will be relatively finer. However, the power consumption will increase with the increase of the rotor speed, which will to accelerated wear of the blow bar and increase the production cost. Therefore, the speed should be appropriately increased in production.
    5. The angle of the counterattack board should be appropriate
    The angle of the counterattack plate has a influence on the crushing force generated by the impact of the material on the counterattack plate. Pay attention to the angle of the counterattack plate, and try to make the material and the counterattack plate perpendicular to the counterattack plate when the material collides with the counterattack plate, so as to increase the productivity of the counterattack.
