High-Intensity Roll Separator Using Permanent Magnets
The induced magnetic roll separators (IMR) require a massive iron yoke to conduct the magnetic flux via the rotating roll and the associated airgaps. The narrow air-gap required for high magnetic field is also apparent. A further complication to the problem with small air-gap is that the roll deflection, due to the strong magnetic force ...
