In practice, a higher number of diaphragms leads to a higher pressure drop across the mill, due to longer mill (∼300 mm longer per diaphragm) (Duda, 1985), and heavier weight of the total ball mill unit. This outcome leads to higher capital costs as well as higher operating costs in terms of specific power consumption when more compartments ...

When a ballmill fitted with a diaphragm is overfed, the mill fills up to a certain level, then stops crushing and discharges any additional feed back through the feed trunnion. Once overfed, it takes from 30 min. to 2 hr. to free itself. Ballmills, therefore, should be provided with a central opening in the diaphragm connecting with the ...
