We have Calculating Ball Charge In A Ball Mill,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

Estimates the charge volume of a grinding mill based on the number of exposed lifters. by counting the number of lifters showing during a mill shutdown and comparing to the total number of lifters including those buried in the charge the fraction of the mill under the charge is determined.
Mill critical speed determination. the critical speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shells inside surface. this is the rotational speed where balls will not fall away from the mills shell.

In grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 andor mill liner wear and tear.
The first order kinetics of grinding occurred for all ball charges and for all samples. as the ball charges and narrow, the size fractions of the samples have different masses. in this research, the grinding efficiency has also been observed through the specific mill throughput per ground product, per unit mass of the ball charge q s
