Grinding Media Wear Rate Calculation in Ball Mill

2017-4-29  Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear

How to choose proper grinding media for your ball mill

2021-2-24  The grinding media in the ball mill is required to have great wear resistance and impact resistance. The material to make the grinding media must be hard, wear-resistant, and not easy to crack. Burr and crack are not allowed on the surface of grinding media, and the out of roundness of the steel ball shall not exceed 2% of its diameter.

A discussion on the measurement of grinding media wear

2016-7-1  A material's susceptibility to wear depends on its physical and mechanical properties as well as on environmental factors, i.e., the conditions to which the material is exposed .In other words, the wear is a function of the tribosystem (), which is made up of four elements: body, counterbody, interfacial element and environment.The action of each one of these elements can vary, as well as the
