A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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.
pdf grinding media balls charge calculation in ball mill. Rod Mills zenith the presence of metallic balls or other media dates back to, use of rods as grinding media, grinds ores, coal/ coke, and other, ground in ball mills before separation of valuable minerals, charge typically occupies 35% of the internal shell
The ball mill abrasion test (BMAT) promises to offer accurate prediction of relative service lives of wearresistant alloys for liners and grinding media in mineral grinding environments.
Abstract: Based on the research on the grinding media motion in the ball mill, the discrete equation of grinding media motion about ball mill is established and the motion regimes of grinding media is simulated using the discrete element method (DEM) with simplifying the contact model of grinding media and rock material.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. 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.

Calculate and Select Ball Mill Ball Size for Optimum Grinding Based on his work, this formula can be derived for ball diameter sizing and selection: Dm = 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm.
Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

Grinding Ball Mills. 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.
