赤铁矿磁选机的工作原理：将0.04—5毫米的原矿送入上料斗，经过振动电机振动布料，出料量可通过手轮来进行精确调整。磁辊通过调速电机拖动，转速的快慢通过调速表来进行调节，可控制磁选机的产量和精矿品位。

The working principle of hematite ore separator: 0.04 - 5 mm of the ore into the hopper, vibrating motor through the cloth, feeding amount can be precisely adjusted by hand wheel. Magnetic roller through the speed motor drive, the speed of the speed of the speed of the regulation, can control the magnetic separator output and concentrate grade.
