Eriez Magnetic Drum and Drum In-Housing Separators
Eriez magnetic drums have been used for many years in scrap metal yards to separate iron and steel from other materials. Using our sophisticated design software and unique magnetic circuits, Eriez has once again provided scrap drums with deeper magnetic fields to reclaim ferrous materials in shredded car bodies, scrap metals, municipal solid waste, wood waste, slag, incinerator bottom ash, foundry sand and minerals processing applications.

Principle of Operation
As material reaches the drum, the magnetic field attracts and holds ferrous particles to the drum shell. As the drum revolves, it carries the material through the stationary magnetic field. The nonmagnetic material falls freely from the shell, while the magnetic particles are held firmly until they are carried out of the magnetic field.
Three Drum Separator Models Available
Type CC - Criss-Cross Circuit Drum
Type CC Model Drum Separators have a unique “criss –cross” magnetic circuit. A powerful permanent magnetic field uniformly covers the entire drum width to ensure maximum tramp iron removal. The smooth stainless steel shell with single wiper strip assures positive tramp iron discharge and a minimum of product carryover on powdery or cohesive materials.
Type RE - Rare Earth Drum
Rare Earth Drum Separators should be used for applications where a high degree of product purity is required. Rare Earth Drums are effective in removing very fine ferrous particles, locked particles, and even strongly paramagnetic particles. Magnetic lines of flux are concentrated in each internal pole, creating an extremely high–gradient magnetic field.
Type A - Agitator-Type Drum
Type A Agitator–Type Drum Separators automatically removes difficult–to–separate magnetic contamination from nonmagnetic materials. This Drum (available with or without HFP housing) has a specially designed magnetic element that causes agitation of materials passed over it. The agitation moves the material in and out of a set of magnetic fields, and thereby physically shakes nonmagnetic materials from ferrous materials, even when entangled.
