On the whole, ball mill is suitable for grinding all kinds of ores and other materials in ore beneficiation, building material and chemistry and the grinding types can be divided into dry type and wet type. According to the ore discharging manners, ball mills can be divided into lattice type and overflow type.
The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
