Ball mill overview and ball mill media
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits.
Grinding of materials in a tumbling mill with the presence of metallic balls or other media dates back to the late 1800's. Since that time, SBM and its predecessor companies, MPSI, Sala, Marcy, Hardinge, Kennedy Van Saun (KVS), Denver Equipment, Allis Chalmers, Boliden Allis, and Dominion Engineering, have designed and manufactured more than 8,000 grinding mills.
The steel shots, balls and beads - ball mill media - are preferred for contamination free and speedy (dry / wet) milling, grinding of solids, liquids dispersion and fine particle size reduction, homogenization of fillers and raw materials, attrition and pulverizing applications in ball, vibro, dyno, pearl, bead, pebble, attritor and small-media mills, vertical or horizontal.
Alloy steel media is particularly suitable, because of its high relative density and hardness, for crushing and mixing heavy and hard materials. Also where high pressure and impact grinding or crushing methods are employed. The forged steel media balls also find advantage in reducing particle size and fine dispersion of highly viscous fluids.
Stainless steel balls and other shapes are used for grinding applications where absolutely no iron contamination is permissible, specially in food products.
Steel grinding media finds advantage where:
- High wear and chemical resistance is required.
- Generation of heat is crucial to the milling and dispersion process.
- Contamination free and speedy (dry / wet) milling is important.
- Crushing and mixing heavy and hard materials is undertaken.
- High pressure and impact grinding or crushing methods are employed.
- Reducing particle size and fine dispersion of highly viscous fluids is required.

Ball mill is the key equipment for fine powder grinding after the crushing process, which is is widely used in powder-making production line, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics . The can grind various ores and other materials with both dry type and wet type.
