Exposure may occur from handling lead pigs while loading the mill pots or the ball mill. Lead oxide dust may spill or leak from trunnion seals, bearing seals, conveying systems, and transfer points. Exposure to lead may occur when drossing the lead pots during the Barton process (Figure 1) and during maintenance operations that require entry into the pot for cleanout.

This sizereduction operation can be divided into two major categories depending on whether the material is a solid or a liquid. If it is solid, the operations are called grinding and cutting, if it is liquid, emulsification or atomization. All depend on the reaction to shearing forces within solids and liquids. ... It includes ball mills, in ...

Calculations: 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, nc = rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/ = % of critical speed.
