Dry separation strong magnetic roller for iron removal

The utility model discloses a dry separation strong magnetic roller for iron removal. The dry separation strong magnetic roller comprises a roller body and rotating shafts at the two ends of the roller body, wherein multiple rows of magnetic systems are arranged on the peripheral surface of the roller body, each row of magnetic systems are formed by an even number of arc-shaped magnetic blocks, the arc-shaped magnetic blocks are fully arranged along the peripheral surface of the roller body, and magnetism gathering sheets are arranged between the adjacent arc-shaped magnetic blocks, and the polarities of abutting joint ends of the adjacent arc-shaped magnetic blocks are identical. When magnetic materials in non-metallic materials pass through the strong magnetic roller, all the magnetic materials are removed, so that the purity of the non-metallic materials is improved. The dry separation strong magnetic roller has high magnetic field intensity and strong catching capacity, is suitable for removal of impurities and iron in the non-metallic materials with very little iron content and purification of the non-metallic materials, fills up the blank of the kind of magnetic rollers and is worthy of wide popularization and application.
