Mechanical reduction methods, impact, attrition, shear ...

Shear. This consists of a trimming or cleaving action rather than the rubbing action associated with attrition. Shear exploits the fact that the ratio of compression strength too tensile and shear strength in the majority of rocks is approximately 10:1. Low speed sizers break the rocks in tension and shear by its chopping action. Shear crushing ...
