The dry magnetic separator generally does not need a tank for accommodating the slurry, and the material is conveyed by a vibrating feeding device, and a dustproof device is often provided. The wet magnetic separator has a tank to accommodate the slurry to maintain the fluidity of the material, and the pump is usually transported by a slurry pump.
Magnetic separator is used to separate either valuable minerals from non magnetic gangue,e.g. magnetite from quartz,or magnetic contaminants or other valuable minerals from nonmagnetic values,based on the difference in magnetic properties between the ore minerals.The property of a magnetic separator that determines its response to a magnetic ...
Materials such as nails, rust, scale, bolts, welding rods, and other contaminants are no match for Moley Magnets Separators. We offer all types of magnetic scrap metal separator systems such as eddy current separators, electrostatic separators, vibrating screens, wire stripping machines, and more.
Dry Separation at Finer Sizes
When a minus 325 mesh fraction is tested, a separation sometimes occurs, but in most cases the feed passes through without separation. Response at higher frequencies was investigated with a smaller ¾ inch cross section U shaped magnet core 1 . Separation was performed with a nonmagnetic nonconducting plane surface 3 moved manually across the magnet pole as illustrated by the direction arrow 4. When separation occurred, the nonmagnetic mineral 5 would move with the plane, and the magn...

Application of alternating and intermittent current to magnetic separation at a relatively high number of ampere turns was made possible by special electronic circuits. Actual power losses are low and include the I²R loss, which is the same that occurs in direct current magnetic separation, and the core loss, which has a magnitude corresponding to the I²R loss. Minerals may be dry separated close to the minus 325 mesh size at 60 hertz frequency and possibly at smaller particle sizes at higher frequency. In the wet separation of minus 325 mesh feeds, intermittent current provides for complete release of the magnetic fraction during the discharge cycle. For matted fibrous and magnetically coagulating feeds, a cross belt separator with an intermittent magnetizing current provides efficient separations.
