Roller Crusher is mainly used for secondary and fine crushing to materials below middle hardness, such as coking coal, clinker mineral, limestone, metallic and nonmetallic ore. It is best suitable for intermediate and fine crushing among small and medium size metallic and chemical industry, which can make the minimum grain size below 100mesh. Besides, roller crusher is with simple structure, operation convenience, and stable performance. Also it can make target grain size by adjusting interspaces between two rollers.

Roll Crusher is made up of two parallel cylindrical rolls, which rotate in two different directions. When materials are put into the crushing chamber, which will touch the rollers and then be pulled between rollers because of friction, they will be crushed fully. The whole process is continuous, and the crusher has strong discharging force, so that even wet materials can also be discharged successfully.
