Addition of pebbles to a ball-mill to improve grinding

2017-4-1  Pebble-milling is used on some mines for secondary grinding, to reduce operating costs. However, the availability of pebbles is essential and pebble storage is required. The pebble mills need to be much larger than ball mills, to draw the same power, and hence it is not easy to change from one type of milling to the other.
