Four roll crusher 900×700 mm
Four-roll crusher is a kind of simple structure, compact, lightweight medium crushing, fine crushing, coal crushing particle size regulation range is large, with the device and function of roller wear repair, strong adaptation to material moisture, smooth discharge. Used for crushing limestone, marl shale, brick, slag, clinker, feldspar, coke, etc.
The operating principle of the four roll crusher is to use the high extrusion pressure and shear force generated by the relative rotation of four high-strength wear-resistant alloy rolls to crush the material. The four-roll crusher combines primary and secondary crushing of materials, has a compact structure, uniform particle size of crushed materials and a lower overgrinding ratio. It is suitable for fine crushing of hard and medium-hard materials with compressive strength less than 200 MPa and moisture content less than 30%.
