Jaw crusher is widely used in crushing the medium particle size materials of varieties of minerals and large materials, and it is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and other industries.
Impact crushers are also known as impact breakers or impact crushing machines. It can crusher the material whose side length is below 100-500mm and highest compressive strength can reach to 350Mpa.
Cone crushers are also known as cone breakers. Compressive strength of cone crusher is no more than 250MPa. Cone crusher is widely used in mining, metallurgy, building materials, chemicals and other sectors to crush hard and medium hard materials.
Hammer crusher is composed of chassis body, rotor, hammer, back liner, sieve, etc.. It is suitable for conduct coarse, medium, fine crushing for materials with the compressive strength less than 180MPa like limestone, coal, gypsum, shale and other types of brittle materials.
Roll crusher (roller crusher) is suitable for the fine crushing of the materials with feeding size less than 110mm, and finished particle size 3-30mm.
Compound crusher is also known as combination rock crusher. Compound crusher is mainly used for medium or small cement or clinker crushing.
