  • Addition Of Pebbles To A Ballmill To Improve Grinding

    Addition Of Pebbles To A Ballmill To Improve Grinding

    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.
