Dry Drum Magnetic Separators from Multotec are used in the dry separation of ferromagnetic ores. These separators facilitate a more efficient milling and processing operation through an initial upgrade of the desired feed material, delivering a more productive plant for a lower cost per processed ton.
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.
Eriez Dry High Intensity Rare Earth Roll Magnetic Separator . With the ever increasing demand for high purity feedstocks used in manufacturing, Eriez offers its Dry High Intensity Rare Earth Roll Magnetic Separators. These provide maximum efficiency in the separation of weak magnetic particles for product purification applications.
According to the state of the material, the magnetic separator is divided into dry type magnetic separator and wet type magnetic separator. Dry magnetic separator refers to the material keep dry, dont need to mix with water in the magnetic separation process. The material for wet magnetic separator must be mixed with water or other media ...
Induction type high magnetic force separator KID R For removal of weak magnetic bulk materials. 2.6 T max. Cross belt type high magnetic force separator KID B Small capacity and less mixture of raw materials in removed iron. Induction type separator KID Eﬀective for removing iron from casting sand.
Roll Type Magnetic Separators The rare earth roll, generating magnetic field intensities, is very effective for concentrating or removing weakly magnetic minerals from a dry process stream. The rare earth roll magnetic separator is designed to provide peak separation efficiency and is typically used when a high purity product is required. The roll is constructed of thin neodymium boron iron ...
