Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. These mills are sized from 2 t/h to 30 TPH for wet grinding and from 0.5 t/h to 30 TPH for dry grinding.

Lead: Battery Manufacturing eTool
Lead oxide, which is used to create the paste used on the battery plates, is either produced by the Ball Mill Process or the BartonLike Process.It may also be purchased from an oxide producer (see receiving). The major source of lead exposure in the oxide production process comes from leaking equipment and system upsets.

Ball Mill Operating Speed
The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
