The strong magnetic field sorting machine is divided into wet type and dry type according to working conditions; electromagnetic and permanent magnets are classified according to magnetic source; and disc type, roll type, flat ring type, vertical ring type and induction roller type are classified according to the equipment structure.
1. Dry disc type strong magnetic separator
Dry Intensity Magnetic Separator single disc disc, double disc and three three kinds, suitable for separation of weakly magnetic minerals, such as crude tungsten concentrates containing a noble metal minerals, iron titanium ore, allophane, and monazite Mixed concentrates are re-selected. The selected material size is less than 2mm.
Second, the roller type strong magnetic separator
The roller type strong magnetic separator has electromagnetic (for example, CGDR-34 electromagnetic pair roller strong magnetic separator) and permanent magnet (for example, CGR-54 permanent magnet double roller strong magnetic separator). Its magnetic induction intensity is 1500~2300mT, suitable for processing weak magnetic minerals with a particle size of 3mm, and the processing capacity is 1~2t/h.
Third, induction roller type strong magnetic separator
Induction roll strong magnetic separator electromagnetic and permanent magnet, dry and wet divided, mainly used for sorting of manganese ore coarse particles, also be used for sorting coarse weakly magnetic iron minerals. Several induction roller type strong magnetic separators commonly used in the industry are listed in Table 1.

Fourth, wet flat ring strong magnetic separator
The wet flat ring strong magnetic separator is widely used at home and abroad. The foreign countries are mainly DP type Jones strong magnetic separators. There are mainly ShP type and SQC type strong magnetic separators in China.
A ShP type wet magnetic separator
ShP type strong magnetic separator is a wet double-disc flat-ring magnetic separator widely used in China, mainly used for the selection of weak magnetic minerals. Compared with other types of strong magnetic separators, the machine has better sorting index, large processing capacity, reliable operation and low production cost. The upper and lower plates overlap, and can be combined into coarse-sweep or coarse by free flow without slurry pump. - Fine processes. The effective recovery particle size ranges from 0.02 to 0.18 mm, and the recovery effect of less than 0.02 mm, especially less than 0.01 mm, is poor.
The equipment requires a strong magnetic mineral content of less than 3% in the feedstock, and must not contain more than 1mm of ore and other impurities; the feedstock concentration is generally 35% to 50%. Therefore, a weak magnetic field magnetic separator, a slag removal screen, and a concentrated dewatering equipment should be provided before the strong magnetic separation operation. [next]
The technical performance of the ShP type strong magnetic separator is shown in Table 2.

B SQC type wet magnetic separator
The SQC type wet magnetic separator is a single sorting adhesive disc flat ring strong magnetic separator. According to the diameter of the sorting ring, there are two pairs, four pairs and six pairs of sorting magnetic poles. The machine uses a copper water-cooled pipe and the exciting coil. Due to the small number of turns of the coil, the body is lighter. The sorting apparatus may be used to limonite, hematite weakly magnetic minerals, wolframite, supporting tin ore, used for small and medium beneficiation plant. Its technical performance is shown in Table 3.

Five, wet vertical ring strong magnetic separator
Wet vertical ring magnetic separators are available in single and double rings. The device adopts the lower feeding and the upper discharging method, the magnetic magnetic medium is pure iron ball and the discharging point is away from the magnetic pole, so the magnetic material blockage of the medium can be alleviated. The equipment can be used as a sorting device for fine-grained weak magnetic iron ore and manganese ore. The technical performance is shown in Table 4.
