how to estimate the wear rate for Ball mill - Page 1 of 10
Re: how to estimate the wear rate for Ball mill. Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

grinding media | Magotteaux
High-Chrome media has a superior performance and creates steady milling conditions due to its low wear rate. For each specific alloy there is a constant hardness of all grinding media. This creates a positive influence in the down-stream process. high-Chrome media is suitable for both wet and dry ore applications in ball mills and tower mills.
Why select high chromium alloy cast ball for cement industry?
During use, the surface hardness of the sphere will be further improved, and the wear resistance will be enhanced. At the same time, it can increase the production capacity of the mill, and increase the specific surface area of the cement and the recovery rate of concentrate.
