A discussion on the measurement of grinding media wear ...
3. Conclusion. This article aimed to review and discuss the available literature on the wear of grinding media. The consumption of the grinding media represents an expressive part of the grinding operational costs, reaching up to 50% of it. During grinding, a combination of abrasion, corrosion and impact results in wear of grinding media.

calculation for grinding media in ball mill
Optimization of mill performance by using. This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate a variation in total ball angle can be detected and linked to grinding efficiency and charge expansion this could help the operator to make the right decision and keep the mill
Optimization of mill performance by using
From 74% the media angle exponentially increases with pulp solid content. Unstable milling conditions starts to occur. The Sensomag® clearly detects the load expansion. (Figure 8.) This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate.
