McLanahan Single Roll Crushers

The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 6:1 ratio of reduction while producing a considerably lower percentage of fines. When properly fed in the direction of the roll rotation, the crushing action is carried out along the full width of the curved crushing plate, which ensures maximumRoll Crushers. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of Crusher an overview ScienceDirect Topics
