Formula to calculate grinding media wear rate for cement mill
Now using standard formula we can calculate grinding media wear rate: Wear Rate (g/kWh) = 0.042 * H * D^0.67 * η ... In order to calculate the grinding media wear rate for a cement mill, we first need to understand the wear mechanism of grinding media. The wear of grinding media is determined by the abrasive properties of the material being ...

coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill. For example, when 60% of the solids in a ball mill is coarse, then the coarse solids inventory * in the mill is 60%, and only 60% of the mill

Variables in Ball Mill Operation
The formula for critical speed is CS = 1/2π √(g/(R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√(R-r). ... Mill performance is based on mill diameter and length only increases or decreases capacity. The Slice Mill is simply a mill of ...

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 …
