Pulverizer, the large size of the solid raw material is crushed to the required size of the machinery. Grinder by rough waves, crushing, wind conveying device composition, to achieve the purpose of shredders in the form of high-speed impact. The use of wind energy once into a powder, the abolition of the traditional screening procedures. The main applications in a variety of industries such as mining, building materials.
The grinder can be divided into the primary crusher, crusher, grinding machine, ultrafine mill, straw mill, wood grinder according to the size of the material of scrap or broken system. Nip external force applied to the solid in the process of crushing, shearing, impact grinding four kinds. Nip in the rough, broken, suitable for hard material and chunks of broken material; smash cut mainly used in crushing, suitable for the toughness of the material; impact is mainly used in secondary crushing, grinding, ultrafine grinding, fitness grinding, crushing brittle materials; mainly in the fine grinding, fine grinding, suitable for small pieces and fine particles smash.
