Roll / toothed disk crushers
The main working element of the roller crusher is a roll rotating on a horizontal axis. The material to be crushed is fed from above, tightened between the roll and the lining of the crushing chamber and as a result it is crushed. The surfaces of the rolls can be smooth, fluted and toothed. Crushers with smooth or fluted rolls are used for crushing of medium strength materials (qсж=150); toothed roll crushers are used for crushing of black coal and other low-strength materials. The size of the crushing product of a roller crusher depends both on the size of the output gap between the rolls and on the type of surface of the working bodies.
