　　The impact crusher can crush a variety of stones into coarse, medium and fine pieces, and has been widely used in the production of construction aggregates in railway, highway, electric power, water conservancy and other industries. When using the impact crusher, sometimes there is a large amount of stone powder when crushing the stone, why is this?

　　We * understand the reasons for the excessive amount of stone powder:

　　1. The impact crusher mainly uses impact energy to crush materials. The rotation of the rotor in the machine room is used to drive the hammer head to rotate to strike and collide with the colliding stones to break them. The stones collide with each other under the action of the rotor to form a large stone vortex. Increase the collision between materials. During this process, the rotor rotates to bring out a large amount of air flow, so that the stone powder particles fly out, and the phenomenon of stone powder overflow occurs. In addition, when the impact crusher is working, in addition to the rotation of the rotor to bring out a large amount of airflow, which makes the stone powder fly out, the crushed materials are mainly d by multi-stage crushing and grinding in the crushing cavity. The degree is sm , and the powder particles are easy to fly out during the operation.

　　2. During the crushing process of the impact crusher, the amount of dust not only increases, but also the impact plate will be worn for a long time, or the surface of the impact plate will f off, which will cause the impact crusher to seal. ly reduced, aggravating dust pollution.

　　3. When the impact crusher crushes the material, it is d by multi-stage crushing and grinding in the crushing chamber. The crushed material has a sm fineness, and the powder particles are easy to fly out during the operation.

　　The method to solve the excessive amount of stone powder:

　　1. When users use it, they can be equipped with additional dust removal equipment, or add a closed cover, and can also add a sm amount of water before the material enters the feed port of the impact crusher to wet the material or directly add a dust removal humidifier to cooperate with the work.

　　2. Regularly check the parts of the equipment, such as the tightness of the lining plate, the machine casing and whether the screws at the connection of each device are loose, etc. Regular maintenance and repair of the machine will ly reduce the amount of dust, and also Can improve work efficiency.
