Predicting the crushability of rocks from the impact ...

2010-8-1  The crushability of rocks depends mainly on the crusher type and properties, and geological characteristics of rocks. Physico-mechanical properties, mineralogical and textural features, structural properties such as microcracks, cleavage planes and schistosity are the geological characteristics affecting the rock crushability.

CRUSHABILITY OF AGGREGATES

The jaw, gyratory, and cone crushers are considered most effective when crushing rock that is tough and abrasive and minimum fines are desired. The shear crusher gives a slicing action and is usually used in combination with one of the above compression-type crushers. A typical example is the single-roll crusher.
