The trunnion in a Ball Mill is responsible for discharging material from the mill through the outlet side. When the helix angle is greater than the angle of repose, the balls will roll down, while a smaller helix angle causes the balls to rise. The trunnion's mass flow rate is dependent on the comminution index W.

The two types of ball mill in general use are the grate mill and the openend mill. Most manufacturers make both kinds; the difference between them is that the grate mill has a steel grid clear across the discharge end, but the openend mill has only an open trunnion at the discharge end, through which pulp flows freely.
