Impact crushers mainly utilize the rotation of the rotor within the chamber to drive the hammers to impact and crush stones. The stones collide with each other under the action of the rotor, forming a large stone vortex, increasing the collision between materials. During this process, the rotor rotates rapidly, generating a large airflow, causing fine stones to spill out and causing dust pollution.
When the impact crusher is working, in addition to the large amount of airflow generated by the rotor rotation causing stone powder to fly out, the crushing of materials is mainly achieved through multi-stage crushing and grinding within the crushing chamber. The material is crushed to a relatively fine size, making it easy for powder to fly out during operation. To solve the problem of high stone powder production during impact crusher operation, users can equip the machine with additional dust collection equipment, add an external enclosed hood, or add a small amount of water to wet the material before it enters the impact crusher’s feed inlet, or directly use a dust collector and humidifier in conjunction with the operation.
To reduce the amount of stone powder generated during the operation of an impact crusher, regular inspections of various parts of the equipment should be conducted. This includes checking the liners, the sealing of the machine casing, and whether the screws at the connection points of various devices are loose. Regular maintenance and repair of the machine will greatly reduce dust levels and improve work efficiency.
