The Greenwood drum magnet is similar to the housed drum magnet but is supplied without the housing. It is designed for the continuous extraction of ferrous metal contamination from dry bulk material. Material is fed uniformly onto to the surface of the drum from a conveyor, vibratory feeder or chute work, ensuring continuous contamination removal. As the outer shell rotates, clean product is allowed to free fall from the drum while powerful magnets hold ferrous contamination to the point where the magnetism ends, discharging the metal under the drum, thus ensuring separation.

Metal contamination (Black) is separated from the clean product (Red)

Ideal for free flowing dry products such as granules, grains, minerals and powders.

We manufacture the drum in a:
Standard Ferrite Version – for general tramp iron contamination such as nuts and bolts

High Intensity Version – for fine paramagnetic materials where a greater level of protection is required.
