Background

As the name implies, a magnetic separator is a device that uses the difference in magnetism of the materials being separated to effect separation, with particles of different magnetism moving along different trajectories, thereby enabling the mixture being separated to be separated into two or more separate products as desired. Ores mined from mines all have different magnetic properties, and therefore magnetic separators have very wide use in the mining industry. In the prior art, the ore species separated by the magnetic separator can include various ores such as magnetite ore, limonite, hematite ore, manganese siderite, ilmenite, wolframite, manganese ore, iron placer ore, kaolin, rare earth ore and the like.

According to the dryness and wetness of the ore, a dry magnetic separator and a wet magnetic separator can be respectively adopted. The wet magnetic separator needs to mix the mineral to be separated and liquid such as water into slurry for separation, is relatively simple to operate, and is the most widely applied type of magnetic separator at present. Along with the demands of saving water resources and the like, the development of the dry magnetic separator is more and more emphasized, and the problems of material blockage, poor separation effect and the like caused by magnetic wrapping, magnetic agglomeration and the like do not exist because water is not needed, so that the treatment capacity and the separation effect can be greatly improved. In order to improve the processing efficiency or simultaneously meet various separation requirements, the magnetic separation is performed continuously in layers by using a plurality of magnetic roller structures, and the magnetic roller structures are fixed by a frame, so that the multi-layer frame type dry magnetic separator is referred to herein.

Chinese patent application CN105797845A discloses one such dry magnetic roller and its magnetic separator, wherein it is disclosed that a plurality of magnetic rollers arranged longitudinally can be used to perform multiple magnetic separation on minerals to improve the handling capacity and ore removal grade; the longitudinal arrangement can be a vertical longitudinal arrangement or a horizontal staggered longitudinal arrangement; the shell between the adjacent magnetic rollers is provided with a guide baffle plate to collect the materials selected by the upper magnetic roller and then fall into the next magnetic roller for continuous separation.

Although such a multi-layered frame-type dry magnetic separator can perform multiple separations simultaneously to improve throughput and separation efficiency, it has been found that it is very difficult to maintain it. The high load operation during the use necessarily causes the damage of some vulnerable parts and needs to be maintained or even replaced, for example, after the magnetic roller is damaged or has insufficient magnetism, the whole magnetic separator needs to be disassembled to replace the magnetic roller. When the volume and the weight are large, the disassembled magnetic roller usually needs to be lifted to an inspection point by using hoisting equipment such as a mobile crane for maintenance or replacement. This is feasible for the magnet separator of single magnetic roller or individual layer magnetic roller, but in multilayer frame-type magnet separator, especially when the number of piles is very much, the pylon that its frame was located often occupies very big space even is located different floors respectively, and operating space is very narrow and small this moment, is not suitable for hoist work completely, and is very big to the dismantlement work load of magnet separator, probably causes improper damage to other normally operating magnet separators simultaneously.
