Calculate and Select Ball Mill Ball Size for Optimum Grinding

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.

ROLLING MILL PERFORMANCE

known, it is possible to simulate the mill performance This is essentially equivalent to calculating the effective "mill transfer function" and such calculations are performed routinely by Industrial Systems Ply Ltd to characterise the attainable level of perfor-mance such as speed response (subject to constraints on maximum torque on key com.

mill

This gives a torque of T = 190 / 2 x 3141 x 4 = 190 / 25128 = 75 Nm That's about 66 lbin However, unless you can get a motor with a rpm that matches the sweet spot for milling grain, 120-260 rpm, then you'll have to use gears, sheaves, PWM, variac or some other speed controller to regulate the rotational speed of the mill.
