how to charge media in ball mill
Optimization of mill performance by using SciELO
Table I illustrates or quantifies the media charge angle for different liner designs at different mill speed but with constant filling degree (30%). Indeed, as explained previously, at a mill stop, the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle (βstatic = 143°). An online ......

Optimum choice of the makeup ball sizes for maximum ...
For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles; therefore, the size at which the S value becomes maximum, x m, increases as the ball ....
