The MAGQUIP rapid disc separator works by firstly discharging material for a gravity feed hopper or vibrating feeder onto the unit’s 3 belt conveyor and towards the series of one, two or three rotating discs. The magnetic particles are attracted to the zones of high magnetic gradient on the undersides of the discs and carried beyond the edges of the conveyor belt where they are discharged centrifugally into product collection chutes on either side of the conveyor. Product scrapers that are in contact with the underside of the magnetic discs ensure that all products are discharged from the disc before they can re-enter the magnetic field.
The MAGQUIP disc separator discs are adjustable so that the air gap between the discs and conveyor belt can be fine-tuned and varied, this disc adjustment allows best selectivity position to be set. Optimum selectivity can be accurately achieved by combining disc height above belt with adjustment of the current to electromagnetic coils via the control panel.
Distinctly separate grades of magnetic products can be produced by adjusting the angle of the discs with respect to the feed conveyor belt, the discs are normally tilted so that there is a difference of about 1 mm between the leading and trailing edges of each disc and between the adjacent edges of each disc
Separate a series of magnetic particles and minerals from dry granular materials that have varying magnetic minerals and magnetic susceptibilities.
Typical applications include:
Concentration of minerals such as ilmenite, garnet, monazite, wolframite, coltan (columbite-tantalite etc. (minerals for battery and electronics).
Removal of minerals of low magnetic susceptibility from cassiterite, zircon, rutile and scheelite.
Treatment of industrial powders and minerals.
Purification of quartz for glass making and abrasives & refractory minerals.
