How can we calculate wear rate of grinding media ball in coal mill

Apr 21, 2021

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
