For the purification of dry fine or course material containing ferromagnetic and paramagnetic particles.

The Swenco Rare Earth Roll Separator has a magnetic roll as a head pulley. Made of Neodymium Iron Boron magnets the head pulley has a high intensity magnetic field. Material to be treated is fed by a vibratory feeder onto a short centred thin conveyor belt, which presents an even feed of material onto the magnetic roll.

As non-magnetic material is discharged forward of the roll in the normal trajectory, any magnetic elements present are securely held onto the belt by the magnetic force and are discharged down a rear chute as the belt leaves the magnetic field on the underside of the roll. Separation trajectories are set by varying the conveyor speed and adjusting the splitter blades.

Magnetic rolls are available in 4” and 6” diameters, up to a width of 60”. Multiple configurations of rolls are offered giving the non-magnetic fraction a further pass for improved product purity.
