This leads to a narrower size distribution and significantly less slime compared to ball mills Lower critical speeds of 50 - 65 % and coarser product size (i e 50 mm v 15 mm) results in a lower impact environment but decreased abrasion resistance due to the feed size

The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes And the product of the large AG/SAG grinding is either a finished size ready of processing or an immediate size for further grinding in a ball mill pebble mill or a VERTIMILL or a stirred media detritor (SMD)

A ball mill is a type of grinder used to grind blend and sometimes for mixing of materials for use in mineral dressing processes paints pyrotechnics ceramics and selective laser sintering It works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotati

where d b max is the maximum size of feed (mm) σ is compression strength (MPa) E is modulus of elasticity (MPa) ρb is density of material of balls (kg/m 3) D is inner diameter of the mill body (m) Generally a maximum allowed ball size is situated in the range from D /18 to D/24 The degree of filling the mill with balls also influences productivity of the mill and milling efficiency

Grinding mill include ball mill and rod mill The ball mill works on the principle of attrition and impact The size reduction is done by impact as the ball will drop from the top of the shell Construction of ball mill consists of a hollow cylindrical shell which rotates on its axis

product size to which a mill can efficiently grind depends on the feed material the F80 and media type and size A Vertimill has been used to grind to sizes below 10 lm [11] The phenomenon of overgrinding is largely the result of using media that are too large for the product size generated The smallest ball size typically charged into
