DESCRIPTION

Magnetic Rollers replace the head pulley of a conveyor. They can be manufactured as Permanent or Electro models. In both designs, the magnetic field covers the full 360 degrees of the pulley, ensuring that the conveyed material is always fully exposed to magnetic induction. Magnetic Rollers are custom-built and available in a wide range of diameters and widths. The pulley size is selected based on the installation and application requirements. Magnetic Rollers are widely used as a secondary metal separation unit, especially when maximum ferrous metal recovery or high purity of non-magnetic material is required. Since they replace the main head pulley of a conveyor, they are typically supplied with a rubber belt. The thickness and design of the belt vary depending on the application.

​

During operation, conveyed material reaches the discharge end of the conveyor and enters the magnetic field of the Magnetic Roller. Ferrous metals are attracted and held on the surface of the moving belt. As the conveyor rotates, the captured ferrous material is carried out of the magnetic field, beyond the pulley’s centerline, and discharged into a designated collection area. In some installations, an adjustable non-magnetic splitter plate is positioned under the pulley to ensure clean separation of magnetic and non-magnetic fractions.

​

Magnetic Rollers are available in a wide variety of diameters and widths to suit different applications and installation requirements. The magnetic field is generated either by a permanent magnet assembly or an electromagnetic coil. They are ideal for applications requiring the removal of ferrous metals ranging from small particles to bolt-sized contaminants. Permanent magnet models are manufactured using Ceramic Ferrite or high-strength Rare Earth magnets (NdFeB). Ceramic Ferrite versions generate lower magnetic fields and are ideal for recovering larger ferrous scrap, while Rare Earth designs offer a more intense but shallower magnetic field for capturing fine ferrous particles.

​

In both designs, individual permanent magnetic blocks are mounted on a high-permeability steel back bar and fitted with a heavy-duty stainless steel crowned face cover.
