Roll Magnetic Separator is a roll type dry magnetic separator with fixed magnet having high field intense and gradient. The magnets used in the Roll Magnetic Separators and made of alloys of rare earth elements are more powerful as compared to other magnets. They generate high attraction forces on the magnetic roll due to their properties and special magnetic series. The obtained high magnetic attraction forces have low magnetic sensitivity and therefore they make it possible to separate very fine low magnetic minerals with a high recovery.
