Principle of Operation
A vibratory feeder discharges material onto belt conveyor from the feed hopper and carries it beneath the permanent magnetic scalper and revolving discs.
Zones of high magnetic gradient on the undersides of the discs attract the magnetic particles in the feed and carry them beyond the edges of the belt conveyor where they are discharged into chutes on each side of the conveyor.
Counterweighted scrapers in contact with the undersides of the discs ensure that all particles are prevented from re-entering the high intensity magnetic field.
Adjustment of jacking bolts above each disc alters the air gap between the disc and the conveyor belt, allowing selectivity to be changed. Optimum selectivity can be accurately achieved by combining disc height adjustment with variation of coil current from the control panel.
