Addition of pebbles to a ball

The idea of using a mixture of balls and pebbles at a mill speed suitable for ball-milling was revisited in this investigation using a normal spectrum of pebble sizes (19-75 m) Batch tests in a pilot-scale mill (0 57 m diameter) were used to compare ball-milling to various ball/pebble mixtures
