### Addition of pebbles to a ball-mill to improve grinding

Loveday (2010) reported on batch tests in a laboratory ball-mill (300 mm diameter) to investigate the replacement of a portion of the balls by an equivalent volume of small pebbles (crushed stone 7–25 mm). At the optimum volume of pebbles (25 ) the rate of production of fines (which included the material worn off the pebbles) was the
