Rare Earth Roll
For the purification of dry fine or course material containing ferromagnetic and paramagnetic particles.
The ‘Mastermag’ Rare Earth Masteroll incorporates Neodymium Iron Boron magnets, which are the most powerful permanent magnets available and are built into a composite high-intensity magnetic head pulley.
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 adjusting the conveyor speed using the inverter control setting on the control panel and adjusting the splitter chutes.
Magnetic rolls are available in 75mm, 150mm and 200mm diameters, up to a width of 1 metre. Multiple configurations of rolls are offered giving the non-magnetic fraction a further pass for improved product purity.
Material from 75 micron to 15mm can be treated.
