Magnarolls are employed in minerals and ore processing plants for the removal of weakly magnetic particles from dry granular materials size range from 50 microns up to 100 mm. Typically for the purification and concentration of: Andalusite, Apatite, Bauxite, Calcite, Corundum, Diamondiferous concentrates Dolomite, Feldspar, Fire Clay, Iron Ores, Kyanite, Limestone, Manganese Ores, Magnesite, Mineral Sands, Nepheline Syenite, Quartz, Silica Sand, Sillimanite, Spodumene, Tantalite, Wallastonite.
In the foundry industry they are used for the separation of chrome sand from silica sand. In ferroalloy plants they are used for the recovery of ferrochrome and ferromanganese from slags. Magnarolls comprise of a Hopper with feeder short belt conveyor with Magnetic roll and self tensioning idler geared motor unit driving the magnetic roll via a wadge belt product chute with adjustable splitter blades/s, located beneath the belt support framework.
