The primary target of a magnetic drum pulley is ferromagnetic contamination.

Typical contaminants include:

Iron pieces

Steel fragments

Bolts

Nuts

Screws

Wire

Ferrous machine components

Tramp iron

Magnetic metallic particles

Separation performance depends on:

Magnetic properties of the contaminant

Particle size

Particle shape

Belt speed

Material burden

Magnetic field

Working distance

Material trajectory

Therefore, Power Magnetronics recommends application-based selection rather than selecting a drum pulley only by its nominal magnetic intensity.
