# Ball Mill Ratio

### Ball mill Wikipedia

OverviewVarietiesWorkingApplicationsDescriptionAdvantages of the ball millSee alsoAside from common ball mills there is a second type of ball mill called a planetary ball mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls in the grindi

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
