Different sizes of mill balls
The distribution of mill balls significantly affects grinding efficiency by providing a combination of impact and attrition forces on the material being ground. What is the optimal ball loading capacity in a typical ball mill? In a ball mill with a capacity of 100-150 tons, the maximum ball loading capacity may be around 9.5-10 tons.

Grinding Media Wear Rate Calculation in Ball Mill
In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
