The Ball Mills are on a schedule of 4-monthly overhaul. The main job is the repair or replacement of the lifters and liners, but other work is carried out on the mill to ensure its reliable operation over the following 4 months. In addition, preventive maintenance is carried out on other units in the stream (e.g. the conveyors).

Mill dedicates this last chapter to “the idea of justice” not only because his more sophisticated critics use the idea of justice as evidence that merely calculating the consequences of an action cannot adequately capture its morality, but also because discussing justice allows him to outline a general procedure for dealing with objections to utilitarianism that come from moral instincts.

Ball mill is the key equipment of mineral production process, while its disadvantages include low working efficiency and high energy consumption, which influence the optimization control and energy saving of mineral processing enterprises. 1 The work efficiency is highest while the ball mill load is in the best state. However, the ball mill load is difficult to measure directly.
