The crusher is a manufacturing and processing machine for large-size solid materials. According to the size of the material after the crusher can be divided into coarse crusher, crusher, ultrafine crusher; according to the fineness of the material after the D90 standard, the crusher can be divided into the following four: Crusher (60 below) , Crusher (60-120 mesh), Ultrafine crusher (120-300 mesh), Ultrafine crusher (300 mesh or more).

The ultra-fine crusher is composed of coarse crushing, fine crushing, and wind conveying devices. The crushing of materials through high-speed impact has high efficiency, low power consumption, small footprint, clean and pollution-free, and small one-time investment.

At present, the fine crusher is mainly used to process barite, marble, limestone, activated carbon, bentonite, kaolin, cement, glass, insulation materials, etc. Mohs hardness of not more than 6.5, humidity is below 6% of the non-flammable and explosive Minerals, chemicals, construction and other industries of high-preparation materials.
