## Ball Mill Application and Design Paul O. Abbe

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition. Ball mills have the advantage of being self-contained so operators are not exposed to the product being milled. Ball mills

A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages: • Universality and high capacity. • Permanence of a

The design of a ball mill can vary significantly depending on the size of the required mill, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the “lengthto- diameter” ratio, which frequently varies from 0.5 to 3.5. The starting material can be loaded either through a spout feeder
