2020-12-4 MINERAL PROCESSING MILLING Introduction Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety

Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process.
