Crushing And Grinding Of Ore

Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Grinding (and or milling, which is a form of grinding) is accomplished by abrasion and impact of the ore by the free motion of unconnected media such as rods, balls, or pebbles. Crushing is usually a dry process.
