Permanent plate magnets are used in recycling, quarrying and heavy industries. These units can be placed above flat or trough type conveyors. Large permanent magnetic packs generate deep penetrating magnetic flux fields that attract and remove ‘tramp’ type steel items. This unit is considerably less expensive than electromagnetic units and, as it has no running costs other than cleaning, much cheaper to run. When considering installation points it should be noted that steel belt support rollers will needs to be changed to nonmagnetic ones due to possible flux field absorption. For heavily contaminated materials consider the self cleaning permanent magnetic overband.

Design principle

Powerful magnetic roller separator evenly convey the material to rubber belt rounded on magnetic roller by vibration chute. Because of magnetic force, the magnetic field attracts and holds ferrous particles firmly to the drum shell. Whereas the non-magnetic material is thrown forward by gravity and inertia, thereby achieving the iron automatic separation.

Cleaning

The magnetism cannot be switched off so cleaning has to be done manually using either a scraper tool or gloved hand. To aid cleaning, plate magnets can be supplied with a sliding cleaning plate.
