Drum Magnets (Wet/Dry)
Medium Intensity Wet Magnetic Separator with Con-current tank
Magnetic drum separators have a wide range of applications. They are used in free-fall chutes or after a vibratory chute for powders (even fine powders), granulates, fibers and coarser product streams. They continuously and fully automatically separate ferromagnetic (Fe) particles, such as iron and steel.
A drum magnet is a stationary (180°) magnet segment, around which a stainless steel drum rotates. The magnet attracts magnetic particles that are in the product. The drum carries the attached particles with it to the bottom of the drum. Where the particles drop off and can be collected and carried away. For strongly magnetic particles, carriers are placed on the drum to ‘push’ the particles out of the magnetic field. The advantage of a drum magnet is that it is a continuous cleaning/separating system, in which it is not necessary to stop the product flow to remove the magnetic particles.
