10.08.2022The Milling process The milling process has evolved from wheat being ground between two large stone wheels (although this process does still occur in a few mills). In a roller mill the practice centres around separating the three components of a wheat seed – the white endosperm, the outer bran layers and the wheat germ.

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 of materials which either have end uses
