In any mill the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is seen to be Kick s law.
