continuous ball mills. In an experiment conducted using a wet laboratory continuous ball mill filled with pebbles, cylinders and balls of equivalent volume and a 95% calcite feed combined with a 5% quartz, ball load, density and shape were varied. It was shown that decreasing the ball load by by weight also decreased the residence time by 40%.
