In order to reduce the amount of stone powder in the work of the impact crusher, the various parts of the equipment can be checked regularly, such as the inspection of the liner, the sealing of the machine casing and whether the screws at the connections of each device are loose, etc., and the crusher should be regularly checked. Maintenance and repair will reduce the amount of dust and improve work efficiency.     When the impact crusher is working, in addition to the large amount of air flow brought out by the rotation of the rotor, the stone powder particles fly out, and the crushing of the material is mainly d by multi-stage crushing and grinding in the crushing cavity, and the fineness of the material is small. , During operation, powder particles are easy to fly out. In addition, its working method is mainly d by beating and crushing, which will increase the amount of dust, and the counterattack board will be worn for a long time impact, and what is more, the counterattack board will fall off, which will cause counterattack crushing The sealing of the machine is reduced, and dust pollution is aggravated. In order to solve the problem of the large amount of stone powder in the work of the impact crusher, the user can be equipped with additional dust removal equipment, or an enclosed cover, and a small amount of water can be added before the material enters the inlet of the impact crusher. Wet or directly add dust removal humidifier to work together.
