The crushing ratio is large (usually 10-25, the highest is 50), the production capacity is high, the product is uniform, the phenomenon of over-powder is less, the unit product energy consumption is low, the structure is simple, the equipment is light, and the operation and maintenance are easy. The hammer crusher series products are suitable for crushing various medium hardness and brittle materials, such as limestone, coal, salt, white submerged, gypsum, alum, brick, tile, coal gangue, etc. The compressive strength of the crushed material does not exceed 150 MPa. This machine is mainly used in cement, coal preparation, power generation, building materials and compound fertilizer industries. It can crush raw materials of different sizes into uniform particles to facilitate the processing of the next process. The mechanical structure is reliable, the production efficiency is high, and the applicability is good.
