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 …
The threaded portion of the bolt extends through the shell and is fastened using a hex nut. Between the hex nut and the mill shell is a cup washer and a rubber seal that can extend through the mill shell.
