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.
