Theory Of Crushers Rock

Roll crushers sciencedirect,jan 01, 2016 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.
