The handling of heavy steel balls canCalculate and Select Ball Mill Ball Size for Optimum Grinding,In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

## 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(PDF) A comparison of wear rates of ball mill grinding media,The ball mill abrasion test (BMAT) promises to offer accurate prediction of relative service lives of wear-resistant alloys for liners and grinding media in mineral grinding environments.
