1. Introduction. The kinetics of grinding media wear is estimated based on theories put forward shortly before the second half of the Twentieth Century, as is evidenced in the work of Sepúlveda, which uses the theory of linear wear to calculate specific rate constant research approaches were found such as that of Albertin and Sinatora, in which ball wear showing linear behaviour ...
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.

How to Calculate Charge Volume in Ball or Rod Mill To calculate grinding media charge for continuous type ball mill, M
The presented values show a rapid wear of grinding media, which leads to the diminution of specific charge, with negative effects on grinding process. The throughput of the mill is reduced with 4 – 5 %, because of grinding media wear, even after several days of work. Actual fact shows that the specific charge correctly adopted and ...
From design view the wear displacement h is more convenient than V. With h i =V i /A, the contact pressure p=F/A where A is the area subjected to wear then: h i =k i p s. The sliding distance s can be replaced by s= where v is the mean value for the slide rate and t the running time.
Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. ... The ball size factor, F B, is added to the mall shaft power for mill sizes greater than meters ...
