Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

The centre discharge is located between the coarse and the fine grinding compartment of a tube mill (Fig. 5). The mill is fed from both sides through its hollow trunnions. The material

Optimization of an industrial scale open circuit threecompartment ...

The threecompartment ball mill was modelled by the perfect mixing ball mill modelling approach (Whiten, 1972). Intermediate and discharge diaphragms were modelled by the efficiency curve approach (NapierMunn et al., 2005). Results indicated sufficiently good agreement between balanced and model predicted particle size distributions.

Calculation of The Power Draw of Dry Multicompartment Ball Mills

Equation 1 is multiplied by the factor of A multicompartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments.
