For this particular mill, we suggest a ball recharge of 0.005 balls / hour for the balls with diameters of 30.7 mm and 26.9 mm, while for balls with diameter of 40.5 mm, we suggest a ball recharge of 0.01 balls / hour. From the mill media wear rate obtained experimentally we analyzed the ceramic ball consumption C D SS.

The Grinding Balls will grind the material into powder size of 20 to 75 micron. In mining operations, this will allow for the liberation of gold and other precious metals that are hosted by the rocks. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties, specification and advantages.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
