Rock crushing is a common industrial need, particularly in mineral processing.

There are several machine types for the job, and the choice depends upon the size distribution wanted in the final product.

Briefly, there are hammer mills. You can easily imagine the hammers breaking the rock.

Rod mills, in which the rock and a number of large steel rods are tumbled together.

Rod and Cone which consists of a metal cone inside which a stout rod rotates in a cone fashion.

Ball mills whose purpose is to produce a fine slurry.

In addition there is a small (hand size) rock mill made of tungsten carbide, in which an eccentric carbide mass is wobbled back and forth at high speed. This produces finely ground powders, and is used in lab processing.

Some work is current in using relatively low powered microwaves to pre-fracture the rock along mineral boundaries.
