Ball mills as well as rod mills are widely used in the mining industry on account of their simplicity. Ball mills in particular play an important role in secondary grinding of ores to final particle sizes smaller than 100 µm. The market leader Outotec alone has delivered more than 8000 such mills for the mining industry (Fig. 11).

In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .

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 ...

Wear of grinding media. One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement [3], as the wear of the grinding balls requires their substitution at intervals.

Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...
