Inspired by his creative idea that the novel and most energy efficient grinding concept for fine and ultrafine grinding of industrial calcium carbonate, as developed by Omya during the second half of the last century, might be successfully applied into non white minerals, Fritz Moser, based on his wide ranging experiences from ABB, secured a long term license in …

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
