The function of the diaphragm is to retain the grinding media and allow free passage of the wet pulp or dry material through the perforations. On starting, the pumping action of the diaphragm lifters establishes a gradient within the mill. For grinding dry materials a steep gradient is essential to move the material through the mill.

Fluff cellulose pulp was oven-dried overnight before grinding. A known quantity of the dried fluff pulp was taken and ground one to three times through a laboratory heavy-duty knife mill (Retsch SM 2000, Germany) with a 0.25 mm screen. The knife mill consisted of a cutting blade rotor (1690 rpm, 60 Hz) which was powered by a 1.5 kW electric motor.

Dry grinding has significantly lower media and liner wear than wet grinding; thus, the Fe concentration in the pulp of downstream process for the same mineral is relatively lower after dry grinding. Dry grinding produces rougher surfaces (mechanically activated centers) and more agglomerated particles than wet grinding.
