The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two types of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type depending on different forms of discharging material.

A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods. Then another pilot scale ball

Wet ball milling is similar to dry ball milling, except that a certain proportion of water or absolute ethanol should be added according to different materials in the grinding process. It is mainly used for materials that will not affect the quality in the presence of water, such as non-ferrous metal ores such as gold, copper and copper.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
