Two 1.2 m diameter Pulley Magnets have been manufactured by Master Magnets and supplied to a mining operation in Sweden. The Pulley Magnets are used to extract large tramp metal from iron ore prior to crushing and screening. Removing the tramp metal protects the other processing equipment and prevents damage to conveyors. The mining operation originally purchased three 1.2 m diameter Pulley Magnets in 2015. The latest two Pulley Magnets have been purchased as strategic spares.

In this iron ore application, the conveyors are 1.2 m wide and travelling at 2 m per second. The conveyor is carrying 650 t per hour of iron ore with a bulk density of 2.4 t per cubic metre. As the Pulley Magnets operate as the drive pulley, they are lagged with rubber to provide extra grip on the underside of the conveyor belt.
