Roller mills are used for small and medium crushing of coal, ore, limestone and other materials. Roller crusher (Figure 1) consists of two rolls 3 and 5 of the same diameter, which rotate in opposite directions with equal speed.

Roll crushers consist of two or more adjacent rolls placed parallel to each other and rotated in opposite directions. Single roll crushers are also available which rotate a single roll against a fixed breaker plate. Mineral or rock particles placed between the rolls are nipped and then crushed as they pass between the rolls.
