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, and stainless steel balls.

ENERGY SAVINGS AND TECHNOLOGY COMPARISON USING

A regrind ball mill with a mix of small grinding media The most important parameter to determine the required size of grinding media is the feed size. In Figure 2, the specifi c breakage rate was calculated by Bazin, Parent and Chevalier (2004) and Power reduction in ball mills using small media at the same charge volume of 25 mm balls.

Grinding Media Selection Guide Union Process®, Inc.

Costs Media that may be 2–3 times more expensive may last considerably longer, and therefore, be well worth the extra cost over the long run. The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8” to 1”.

Grinding Medium an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
