A. Gupta, Yan, in Mineral Processing Design and Operation, 2006 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 irregular size.

22/03/2013 · Crushing and Grinding. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. In the nature minerals are usually intergrowth with other mineral species. In order to separate them, they must be unlocked through comminution (crushing and grinding).
