The ball mill was turned so that it was facing vertically upward. The required number of steel balls was poured inside the mill and about 1.5 kg of the sample was delivered into the mill. The mill was closed and the timer was set on the mill panel. The sample was ground for 10 min and the power was switched off. The grinding balls were removed ...

If M is the total mass of the charge within a mill and dM/dt is the rate at which the balls are consumed, the time constant of a mill is θ = - ( Eqn. 1) The ball charge used was 22 tones. The mass of material milled is T hence the ball consumption in kilograms per ton milled becomes: = ( Eqn. 2)
