[0002] Magnetic separator is a mineral separation equipment that uses the magnetic difference of minerals to separate them in a magnetic field. It is widely used in resource recycling, wood industry, mining industry, kiln industry, chemical or food industry. Among them, the drum is one of the indispensable parts of the magnetic separator, which is used to separate the magnetic substances in the material by using the magnetic field.

[0003] In order to increase the service life of the basic drum, it is generally protected by rubber coating. However, the colloid is on the outside. Not only is it easily corroded by environmental moisture due to being in the air for a long time, but it is also easily aged due to friction contact with various materials. It is also prone to local wear and leakage, which has certain limitations. In order to solve the above technical problems, we have designed a wear-resistant magnetic separator rubber-coated drum using aluminum nitride composite ceramic sheets. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber-coated drum of a wear-resistant magnetic separator using aluminum nitride composite ceramic sheets, comprising a drum body, the left and right sides of the drum body are fixedly connected with packaging side plates, a rotating rod is installed through the center of the surface of the packaging side plate, and stable seats are sleeved on the left and right sides of the surface of the rotating rod, the outer ring of the drum body is fixedly installed with diverter ribs, the drum body comprises a drum base layer, the outer ring of the drum base layer is fixedly installed with a rubber coating layer, and the outer ring of the rubber coating layer is fixedly sleeved with an outer ceramic reinforcement layer.

[0006] Preferably, a rubber spring column is installed between the outer ceramic reinforcement layer and the cylinder base layer, and two ends of the rubber spring column are fixedly connected to the inner wall of the outer ceramic reinforcement layer and the outer ring of the cylinder base layer respectively.

[0007] Preferably, the number of the rubber spring columns is several and they are distributed around between the cylinder base layer and the outer ceramic reinforcement layer, and the surface of the rubber coating layer is penetrated by mounting holes for use with the rubber spring columns.

[0008] Preferably, the rubber coating layer is made of polyurethane, the rubber spring column is made of high-cis-butadiene rubber, and the outer ceramic reinforcement layer is made of the same material as the diverter rib, and both are aluminum nitride ceramics.

[0009] Preferably, the number of the diversion ribs is several and they are evenly distributed on the outer ring of the drum body, and the surface of the rotating rod is movably connected to the stabilizing seat through a bearing.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model has the advantages of ceramic reinforcement by arranging a rubber coating layer, a rubber spring column, an outer ceramic reinforcement layer and a diversion rib plate. The diversion rib plate and the outer ceramic reinforcement layer can be located on the outside of the equipment to contact various materials and environmental moisture, so the wear resistance and aging resistance are better.
