The ball mills are operated at a ball charge volume of 3032% and % critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...

A trommel is a rotary cylindrical structure that is rigidly attached to the discharge end of a mill. The intended operation of the trommel is shown schematically in Fig. 1. It contains moulded screen panels or wire mesh and can have different aperture configurations in each axial section depending on the intended duty.

discharge hopper. The blind trommel is a short extension that bolts directly to the discharge flange of the ball mill. The function of the blind trommel is to transport the mill discharge material through the magnetic field. The blind trommel is fabricated from stainless steel and has an abrasion resistant wear liner. The
