Crushing principle and theory. material crushing isongstanding topic. crushing is quite complicated. it is not only related to the nature of the material being crushed homogeneity, hardness, density, viscosity, block shape and moisture content, but also to the selected mechanical equipment.
Since there is no provision for the swelling of broken ore in the crushing chamber, roll crushers must be starvation fed if they are to be prevented from choking. although the floating roll should only yield to an uncrushable body, choked crushing causes so much pressure that the springs are continually on the work during crushing, and some oversize escapes.
The single roll crusher, with its 61 ratio of reduction, is ideal for reducing large feed lumps toedium product size while producingonsiderably lower percentage of fines. the minimum product sizing ofingle roll crusher is generally limited to 23. the crushing is carried out between the full width of the extralong curved crushing plate and the lowspeed crushing roll.
Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. in the secondary and subsequent stages, the material is further reduced and refined for proper size and shape, mostly based on specifications.
