Peripheral Discharge Ball Mills. The several layers of balls lying on top of those next to the shell follow a similar cycle except that, due to relative difference in the two forces, their paths become more nearly vertical. The outer layers, spreading more than the inner layers, increase the area in .
Most discharge via trunnionoverflow; Volumetric loading is similar to that of a ball mill (3035%) Design standards for drive components are more demanding than ball mills; Dry applications feature a peripheral discharge or an airswept arrangement; Typical operating speeds are slower than either SAG or ball mills: 6570% TCS (wet) and 6263% ...
If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
The cost of a ball mill conversion from overflow to grate discharge is ''fairly'' affordable at 65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.
