After crushing the material discharged by gravity itself. This crusher is characterized by only one pressure between the two rollers, , so it has less over crushing phenomenon.
Roll crusher features simple structure, compact and lightweight, reliable, inexpensive, and easy maintenance, and uniform size crushing, grinding small, fine particle size (which can be broken to 3.0mm below). Therefore, suitable for brittle materials and for handling viscous materials (such as tungsten ore), as used in the middle and fine crushing. Roll crusher main disadvantage is the low processing power.
