Roll Magnetic Separator is a kind of dry magnetic separator with high intensity, permanent magnet, roll-type. Roll Magnetic Separator is used for enrichment and purification of materials with a grain size of 0.1 to 25 mm and at the low magnetic sensibility. Magnets made from an alloy of rare earth elements used in the production are more powerful as compared. The magnet with this feature and the special magnet sequence on the magnetic roll consists of high gravitational forces. The resulting high magnetic attraction forces make it possible separation with high efficiency magnetic minerals with low magnetic sensitivity and very fine sizes.
