Sometimes waste rock of high strength is used as pebbles. Pebble mills should always be of the grate discharge type. The energy that can be converted in a mill depends on the total weight of the grinding charge. ... Consequently, pebble mills convert less power per mill volume unit than rod and ball mills. High quality steel rods and balls are ...
