Four Roll Crusher 900×700mm
Four Roll Crusher is a kind of simple structure, compact, light medium crushing, fine crusher, coal crushing particle size regulation range is large, with the device and function of repairing wear rollers, strong adaptability to material moisture, smooth discharge. Used to break limestone, marl shale, brick, slag, clinker feldspar, coke, etc.
The working principle of the four-roll crusher is to use the high extrusion pressure and shear force generated by the relative rotation of the four high-strength wear-resistant alloy rollers to crush the material. The four-roller crusher integrates the primary and secondary crushing of materials, with compact structure, uniform particle size of broken materials, and less overcrushing ratio. It is suitable for the fine crushing operation of hard and medium hard materials with compressive strength less than 200MPa and humidity less than 30%.
