Home; Grinding balls for mining - suitable for all mill applications. Grinding balls for mining are made from various metals such as steel, hard metal and ceramic.However, they are commonly manufactured from steel and steel alloys which have superior resistance to abrasion and low wear rates.Hardness might be between 15 and 66 on the Rockwell Scale or between 85 to 105 on the Vickers hardness
model to ball mill grinding. However, the same models could not be extended to semi autogenous grinding. Simply carrying out pilot scale SAG grinding is a very tedious task. At this time, the discrete element method appeared on the scene. DEM helps in simulating a number of features of SAG mills and AG mills, not to mention balls mill as well.
An experimental laboratory scale ball mill available at the University of Lubumbashi was used in this research work. The ball mill measured 0.305 m in diameter and 0.127 in length. It was driven by an asynchronous motor rated with power close to 10 kW. A schematic of the experimental laboratory ball mill used is shown in Fig. 3.

In this study, we used a planetary ball millin laboratory scale. The powders dis-tribution, the balls distribution, and the wear were modeled using DEM. The simulations of dry mill were conducted by using a standard coefficient of restitu-tion of 0.3 and a friction coefficient of 0.75 (ball-ball and ball-liner collisions) [20].
Finally, with this scale-up procedure it was possible to appraise the plant scale optimization via laboratory scale grinding mill tests. The effects of changing percent solids were assessed in order to improve the industrial mill performance and the optimal value should be in the range from 76 to 80%.
