These dust not only comes from the mining and processing of raw materials such as coal and ore, but also may be caused by wear and vibration during the operation of machines and equipment. If the generated dust is not treated, it will not only affect the physical and mental health of the relevant operating personnel, but also may lead to the decline of mining equipment performance and environmental pollution.
