  • MINERAL PROCESSING MILLING

    2014-2-21 · 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 varietySELECTED MINERAL MATERIALS GRINDING RATE AND ,2013-7-1 · the grinding process. The low efficiency of the grinding process, caused by the grinding media energy dissipation, forces process engineers to search for such a ball composition for which the decrease of the mean particle dimension is the fastest. This will provide an opportunity to use the operation time of the mill more efficiently.
