online live calculators for grinding calculations, Ball mill, tube mill, critical speed, Degree of filling balls, Arm of gravity, mill net and gross power
In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
