Small-Scale Tests to Characterise Ore Grindibility. to that of the ball mill test, as follows: It is common to observe a difference between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore hardness by size (12.5mm for RWI and 3.35mm for BWI), and/or grain size properties.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals. AISI steel grinding balls for ball mill applications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95. Exceptions include Al series 1XXX and Al 6061 which have the same ...

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills. ... And because the ball mill feed grain size is larger, ball mill feeding groove must have a larger slope and height, so that feed smooth.

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. More

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.
