Crushing Technology : Material Size Reduction Methods

Material trapped between a solid plate and a rotating roll is shorn by its contact with the teeth on the roll. Often the sheer crushing is combined with other crushing methods, such as compression, attrition, and impact, for mineral size reduction. For example, single roll crushers employ shear together with impact and compression.
