Exshaw FM2 successfully uses this idea to make the mill sweep dust fine enough for finish cement. However the box is extremely large to accomplish this. As a rule of thumb for cement mills, the air velocity around the discharge trunnion and hood must be less than 4 m/s. In Exshaw's dropout box they strive for about 2 m/s.

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
