New Magnetic Drum Separators From Eriez

The new Electromagnetic and Permanent Magnetic Drum separators from Eriez Magnetics, Erie, Pa., enable automatic, continuous separation of ferrous materials from high-volume and heavy-duty applications, the company says.

Designed for the removal of ferrous material from shredded automobiles, bottom ash, slag and other recyclable scrap, including chips, turnings and stampings, these drums offer a solution to difficult processing challenges, the company adds. “Eriez engineers designed these drums to stand up to even the harshest conditions,” says Dan Norrgran, Eriez heavy industries market manager.

Two types of Electromagnetic drums are available.  The All Electro Agitator type uses a deep field rectangular–core pickup magnet to reach out and grasp the ferrous, and a second rectangular-core agitator magnet to flip or agitate the ferrous, cleaning it of contaminants like loose mud, paper, fluff and trash. A double drum scheme with counter rotation provides maximum cleaning.

Eriez also builds a non-agitating transfer design that uses a deep field radial pickup magnet to convey or transfer the ferrous around the drum shell to the discharge area. When used in top feed schemes, these drums can provide maximum recovery, the company says. Eriez Scrap Drums also feature wider magnetic fields to handle increased tonnages.

All permanent deep field Magnetic drum designs use Erium permanent magnets to project a magnetic field capable of removing ferrous from distances of up to 15 inches (380 mm). The permanent non-electric scrap drums are ideal for applications with limited or unstable electrical power.

A wide variety of diameters, widths and magnetic strengths are available to provide the desired capacity and degree of separation at the lowest possible cost, the company says.
