What is the purpose of crushing, grinding and milling

Crushing involves reducing the ore size from various sizes ranging from particles as big as a human body, or just the size of your head or toe to an average 90 to 140mm for primary crushing or 40 to 55mm for secondary. Note the size depends on the plant design but generally it's a reduction in ore size from about 1000mm to 150mm for clarity's sake.
