3. Comminution and Mill Energy Requirements Comminution includes both crushing and grinding. Initially, ore is reduced in size by crushing rock to a size that makes it manageable. Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Crushing is usually a dry ...
