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
The Kek Cone Mill is recognized as an intermediate energy mill and one of the most versatile size reduction machines in the powder processing industry. Its ability to process a wide range of feed material and produce an equally wide range of product make it ideal for sizing in both wet and dry granulation processes
