### how to estimate the wear rate for Ball mill Page 1 of 10

Dec 08, 2009 With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated. More simply and quite adequate is to keep a record of material ground and of charge added periodically to cover a given level of mill power. By this way you can measure easaly wear of ball/ ton of cement.

### Grinding Media Wear Rate Calculation in Ball Mill

Apr 29, 2017 This formula shows the rate of wear at any instant. Since rate is always equal to the differential of space with respect to time, then R = dw/dt in which dw is the weight of material worn off in a very small interval of time dt. This formula gives the total number of balls of diameter between Da and Db.

### THE GRINDING CHARGE OF ROTARY MILLS

The total wear of grinding media, during the cement clinker (balls of forging steel and hardened with 600 Brinell, and cylpebs by special iron) is of 162 308 g/t of cement (4.4 8.4 g/kWh) [2]. The presented values show a rapid wear of grinding media, which leads to the diminution of specific charge, with negative effects on grinding process.
