Read MoreThe 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 mm). Batch tests in a pilot-scale mill (0.57 m diameter) were used to compare ball-milling to various ball/pebble mixtures.
Read MoreApr 01, 2017 Many ball-mills are designed as overflow mills, and the resultant excess of pulp may affect the efficiency of the ball-pebble mixture. 2. The theory developed for batch tests involving pebbles, has produced data which are consistent with published data.

Read More1. If the rotating speed is low, the ball in the ball mill will be lifted to a small height. The ball will slide down from the top of the ball load by the gravity of the ball itself. At this time, the impact force of the ball is very small, but the grinding effect is strong. The ore is mainly peeled and crushed, and the grinding effect is not high. 2.
