Head roller magnets separate ferromagnetic (Fe) particles – such as iron or steel, or even weakly magnetic particles such as processed stainless steel – fully automatically and continuously, from coarse to extremely fine fractions with a small layer thickness. A head roller magnet is usually built into the drive roller (end roller) in a conveyor belt and is therefore very price effective.
Operation: The head roller attracts magnetic particles in the product flow and carries them to the underside of the roller. There the particles drop off and can be collected and carried away. For strongly magnetic particles, cleats are placed on the belt to ‘push’ the particles out of the magnetic field.
- The 1800 and 3000 Gauss versions separate Fe particles from 1 and 0.5 mm in the recycling, transshipping and ceramics industries.
- The 6000 and 9000 Gauss versions (high gradients) are so powerful that they can remove very small Fe particles or even weakly magnetic materials, such as stainless steel that has been processed by a shredder or iron dust in the micron range from ceramic materials.
