The double roll crushers have two highspeed, parallel, toothed rollers with a fixed gap between them. As the material passes through them, it is subjected to mostly compression forces and some impacting forces. The low speed sizer is equipped with two toothed rolls. Even though the two rolls revolve slowly in an enclosed chamber, they have a high torque. These teeth are placed in an

Roll Crusheran overview | ScienceDirect Topics

Rotary breakers, jaw crushers, roll crushers, or sizers are used to achieve particle size reduction. Crushing may also improve the cleanability of the coal by liberating impurities locked within composite particles (called middlings) containing both organic and inorganic matter. The crushed material is then segregated into groups having welldefined maximum and minimum sizes. The sizing is
