The Permanent Magnetic Roller Separators has been used successfully in Industrial Minerals applications in CHINA. The Machine incorporates high energy Rare Earth Neodymium Permanent Magnetic Roll Assembly, which is manufactured and assembled under strict quality control and specification to Generate unsurpassed Magnetic Field Gradients. Under this High Intensity Magnetic Field, weekly Magnetic Contamination can be easily removed efficiently.
Principle of operation
Material is fed from the hopper at a controlled rate on the conveyor. As the belt travels around the roll, magnetic particles are influenced by competing centrifugal and magnetic forces. They are thrown from the belt, at a position on the roll where the centrifugal force overcomes the magnetic forces.
Non – magnetic particles are thrown from the belt on their normal trajectory. The particles are diverted by the splitter onto the chutes or outlets. The chutes can be arranged for ‘Non-magnetics’ or ‘Magnetics’ retreatment.

Applications
Remove weakly magnetic particles from dry granular materials. Typical applications are the purification or concentration of :
Andalusite Apatite Bauxite Calcite Corundum Diamondiferous concentrates Dolomite Feldspar Fireclay Iron ores Kyanite Limestone Manganese ores Magnesite Mineral sands Nepheline–Syenite Quartz Silica sand Sillimanite Spodumene Tantalite Wollastonite.
Size range from 75u to 30mm. Special version available for larger particles.
