Magnetic separators are designed to separate ferrous materials from non magnetic materials The ferrous materials are usually impurities of varying particle size and their extraction either improves the purity level of a bulk product or protects sensitive machinery Separation techniques are also used in metal recycling to sort ferrous from non ferrous material and for conveying cans in
·Modern high gradient magnetic separation HGMS initially originated from a magnetic filter patented in 1937 by Frantz [1] in which the ferromagnetic matrix of fine wires or rods was first introduced into a uniform magnetic field to increase the magnetic field gradient by several orders of magnitude [2] The steep increase in magnetic field force H 0 gradH 0
·Minerals 2022 12 1251 4 of 20 Figure 1 Schematic diagram of CT series magnetic pulley structure 1—multipole magnetic system; 2—cylinder; 3—magnetic conductor; 4—belt [8]
·The magnetic separator is a crucial apparatus used in the magnetic separation process [13] It works by making different magnetic materials follow different paths to achieve the separation effect [47] The sorted ore is fed into the sorting space of the equipment and is primarily subjected to the combined action of magnetic and mechanical forces with the ore grains
·The magnetic field gradient of the magnetic gathering medium is equivalent to 10 100 times that of the conventional magnetic separator while the volume of the medium only accounts for 5 10% of the magnetic field space so the processing capacity of the magnetic separator is greatly improved In order to save energy and improve the magnetic
·A magnetic head pulley is a separator by which tramp iron can be easily eliminated from materials on a conveyor belt This separator is designed with either electro magnetic construction or a permanent magnet These comparatively inexpensive separators are readily installed and can achieve continuous tramp iron removal The
·With the increasing decline in ore quality and the increasing demand for high quality raw materials such magnetic separation technologies with higher separation performance are inevitably required by industry and they include the scaling up of current magnetic separators to meet the demand for larger scale and lower cost exploitation of low
