For a rod millball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less ( from a closed circuit crusher) do not apply a rod mill efficiency factor.

The material to be ground passes through the rotating cylinders, and grinding takes place by the impact of and attrition from the grinding balls tumbling inside the cylinder. In early days a ball mill was used in conjunction with a tube mill. The ball mill was short with a large diameter (L/D = ) and very large size grinding media.

Most ores, however, are made up of hard, tough rock masses that must be crushed before the valuable minerals can be released. In order to produce a crushed material suitable for use as mill feed (100 percent of the pieces must be less than 10 to 14 millimetres, or to inch, in diameter), crushing is done in stages. In the primary stage ...

The ore is sent into a singlecylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multicylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.
