At present, there are many types of magnetic separators used at home and abroad, and the classification methods are different. According to different characteristics, the following classification methods are available. (1) According to the magnetic source of the magnetic separator, it can be divided into a permanent magnet magnetic separator and an electromagnetic magnetic separator. (2) According to the strength of the magnetic field can be divided into: 1 weak magnetic field magnetic separator, the magnetic field strength of the magnetic pole surface Ho = 72~136 kA/m, Magnetic force HgradH= (2.5~5.0)×1011A2/m3; 2 medium magnetic field magnetic separator, the magnetic field strength of the magnetic pole surface Ho = 160 ~ 480 kA / m; 3 Strong magnetic field magnetic separator, the magnetic field strength of the magnetic pole surface is Ho = 480~1600 kA/m, and the magnetic field force HgradH=(1. 5~6. 0) × 1013A 2/m3. (3) The medium according to the sorting process can be divided into a dry magnetic separator and a wet magnetic separator. (4) According to the type of magnetic field, it can be divided into constant magnetic field, pulsating magnetic field and alternating magnetic field magnetic separator. (5) According to the structure of the body, it is divided into belt magnetic separator, cylinder magnetic separator, roller magnetic separator, disc magnetic separator, ring magnetic separator, cage magnetic separator and pulley magnetic separator. . Among them, the magnetic field strength and the selection of the medium structure are mainly distinguished. Weak magnetic separator mainly used for sorting ferromagnetic minerals, magnetic iron ore, titanium magnetite, ferrosilicon. In the past, the industry was mostly electromagnetic magnetic system. The shape of the body was mostly tubular and belt type. At present, it is mostly permanent magnet magnetic system and cylindrical shape, and it is widely used in wet applications. In the past domestic and strong magnetic separator aspect mainly dry high intensity magnetic separator for sorting coarse grain size sorting non-ferrous metals and rare minerals, over the past decade, to sorting low grade, fine particle size and disseminated Weak magnetic minerals with complex mineral compositions have been developed in various forms of wet magnetic separators, such as ring, cage, and disc. The medium magnetic field magnetic separator is mainly used for sorting locally oxidized ferromagnetic ore. Huzhou Zhongke Furnace Industry Technology Co., Ltd , https://www.zkfurnace.com
