Roll Crusher - Mineral Processing & Metallurgy
Laboratory Roll Crushers usually follow a primary crusher in the crushing section of an ore concentrating mill, and the primary crusher should be operated in closed circuit with a vibrating screen or other sizing mechanism to supply a correctly sized feed for the crushing rolls. The action of the rolls in crushing is continuous and the rate at which they will crush depends upon the reduction ...

6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed. For close circuit the product is screened with a mesh ...
Double Roll & Teethed Roll Crusher
The roll-centres are octagonal in cross section, each face being provided with a spline groove and a series of tapped holes for securing the chilled- iron wearing plates. These wearing plates have the sledging knobs, or teeth, cast on their outer surfaces. Thus we have a roll surface that resembles that of the one roll crusher, except that the faces of all teeth are sloped instead of radial on ...
