Magnetic particles are attracted by the drum magnet, whereas nonmagnetic particles follow their flight path determined by inertia and gravity. The attracted material is conveyed by the drum shell to the end of the magnetic field and dropped to the other side of an adjustable splitter.
The key part of the Permanent drum magnetic separator consists of a half moon shaped internal magnetic nucleus (made from either ferrite or NdFeB magnets)The other half space is totally non-magnetized.
external drum from high quality stainless steel(This not only enhances the Drums performance but also reduces the magnetic fields in the shaft and bearings, helping to extend their service life. ) that revolves on a shaft around the fix magnetic cores. The magnet attracts magnetic particles that are in the materials. The drum carries the attached metals with it to the bottom of the drum.As drum cover is rotating invariable.There the metals drop off and can be collected and take away. The magnetic drum can be placed on the output of a conveyor belt or below a hopper (unlike the magnetic pulley the magnetic drum is not an integral part of the conveyor).
