Roll Crusher - an overview | ScienceDirect Topics

Single-roll crushers may be either feeder-breakers, or conventional rolls. The rolls on feeder-breakers resemble the cutting head of continuous coal mining machines. Feeder-breakers have very high capacities of up to 2000 tons/h, and are mainly intended for oversize control rather than achieving a high degree of size reduction.

Roll Crushers - ScienceDirect

2016-1-1 · 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.
