Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

SIZE REDUCTION 2. so separation can be carried out 1. occurs in sizes that are too large to be used • Large particles of solids are cut or broken into small pieces • reasons: 3. increases the reactivity 4. reduces bulk of materials for easier handling and for waste disposal
Size Reduction . A ball mill having an inside diameter of 12 ft. and an inside length of 14 ft. is to be used to grind a copper ore. Measurement shows that the distance between the top of the mill and the level surfaced of the ball charged is 6.35 ft.
Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.
In present-day practice, the ore is reduced to a size many times finer than can be obtained with crushers. Over a period of many years, various fine grinding mills have been developed and used, but the ball mill has become standard due to its simplicity and low operating cost. A ball mill efficiently operated performs a wide variety of services.

Milling is a widely used industrial operation common for cases where size reduction of particles is required (Reid et al., 2008).It can also be known as grinding and involves the size reduction of particles smaller than 10 mm.There is a vast range of mill types available commercially and the choice of mill is based on a variety of factors, such as properties of the …
The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
