The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power b. When feed size was 16mm ball consumption was high. When we used 12mm feed it reduced drastically. c. Wt solids in ball mill At high wt solids consumption was high. But at normal wt solids it was low. Similarly consumption depends on operating parameters which need to experienced by an operator or do lab R D tests.

Chat Online### Ball millWikipedia

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 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 For example in the 1980s the largest operating ball mill was 5.5 m in diameter by 7.3 m in length driven by a 4 MW motor. Today ball mills of 5 m plus are commonplace and 7 m ball mills are currently employed on at least two sites. However there are several cases where large ball mills have not achieved design capabilities. One example was
