Detailed product description

Application

Permanent ferrite suspended magnets (block magnets) consume no energy, which is one of the factors that makes them so price effective. These magnets remove ferromagnetic (Fe) particles as small as 0.5 mm (depending on the layer thickness on the belt).

Cleaning

Cleaning of the block magnet is performed manually (by wiping) or through use of an extractor plate (quick cleaning), by swinging the extractor plate away from the magnet; the Fe particles fall off of the extractor plate as soon as they are moved far enough away from the magnet.

Placement

A suspension magnet is hung above a conveyor belt, by means of chains or cables. The addition of these magnets can considerably boost separation yield:

  • Placement over pulley:
    In this configuration the magnet hangs at an angle over the end of the conveyor belt, where discharge of the material occurs. This is the ideal situation, because the bulk flow is ‘broken open’ at this point. When this happens, the iron particles are exposed within the surrounding material, allowing them to be more easily drawn to the magnet. Keep in mind, however, that it is important for the construction directly beneath the magnet to be made of non-magnetic material; otherwise it, too, will become magnetized.
  • Placement over band:
    This position is used for small layer thicknesses (or mono-layers) and when there is no other option due to the potential for magnetization of underlying steel components (such as motors or guide rollers).
