SMALL C. I. W. BALL MILL. The CIW is a Small Ball Mill that's belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears.

Since the feed rate of second stage mills in the Aoshan concentrator was 400 t/h, the total grinding unit consumption of second and third stage ball mills was 13 kWh/t. (3) P = η P 0 where P is the active power of the ball mill (kW); η is the power factor (80% in this paper); P 0 is the installed power of the ball mill (kW).

The power required was 0.8 I.H.P. per ton crushed in 24 hours. The capacity was 62½ tons per day for each set of 8 rolls, and the total cost, exclusive of lighting, breaking, and drying, was 3s. 10d. per ton. The crushed ore was roasted and chlorinated. The rolls have now been superseded by Krupp ball mills.
