Embodiment Construction
[0012] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0013] figure 1 The wear-resistant magnetic separator drum shown includes an inner cylinder 1 , an outer cylinder 2 and a shaft 3 . The inner cylinder body 1 is a cylindrical thin-walled cylinder made of 1Cr18Ni9Ti, and its two ends are provided with coaxial extension shafts 3 . The outer cylinder 2 is coaxially compounded on the outer wall of the inner cylinder 1, and the outer cylinder 2 is made of alumina ceramics, and the wall thickness of the outer cylinder 2 in this embodiment is 3mm. In the present invention, the materials used for the inner cylinder 1 and the outer cylinder 2 are materials that are not magnetized, which is conducive to improving the quality and efficiency of iron ore selection, and the outer cylinder 2 that is in direct contact with the iron ore has particularly good wear resistance Advanced ceramic materials,...

The invention discloses a wear-resistant magnetic separator roller. The wear-resistant magnetic separator roller comprises an inner roller body, an outer roller body and a shaft, wherein the inner roller body is a cylindrical thin-wall roller, the material of the cylindrical thin-wall roller is austenitic stainless steel, and two ends of the inner roller are provided with an extended shaft having a coaxial structure; and the material of the outer roller is ceramic, and the outer roller is coaxially sleeved on the outer wall of the inner roller. A case that above materials of the inner roller and the outer roller in the invention cannot be magnetized is in favor of the improvement of the careful selection quality and efficiency of iron ore; and the material of the outer cylinder directly contacting the iron ore is ceramic having a very good wear resistance, so the service life of the roller is substantially improved, the maintenance workload during production is reduced, and working hour saving and use benefit increase are realized. The wear-resistant magnetic separator roller is suitable for magnet separator rollers of various specifications.
Description
technical field [0001] The invention relates to iron ore beneficiation equipment, in particular to a wear-resistant magnetic separator drum with external ceramic sleeves. Background technique [0002] Magnetic separator is an indispensable equipment for iron ore beneficiation. In order to improve the quality and efficiency of beneficiation, the magnetic separator drum is not allowed to be magnetic during use. In the prior art, stainless steel or non-metallic materials are generally used to manufacture magnetic separator drums, and the drums of such materials can completely avoid being magnetized. However, the wear resistance of such materials cannot meet the requirements for the use of magnetic separators. In the prior art, there is a technical solution that can better solve the wear-resistant problem. It is to place a layer of rubber sleeve on the outer wall of the drum, and use its wear-resistant performance to make up for the deficiency of stainless steel. However, the ...
