Dry drum separators are used for iron ore and coarse mines’ metal purification and enrichment applications. The magnetic sensitive material is held on the drum by the magnetic drum and is discharged to the metal material area by the separator, non-magnetic material is supplied to the main part through the drum. The system that provides homogeneous distribution to the drum surface with the vibrating feeder provides high productivity at the desired capacity with adjustable magnetic area strength and drum rotation speed. Manyet dry drum magnetic separators have adjustable magnetic area strength on drum surface. It allows that change effective Gauss for variable material and related magnetic sensitivity.
