Magnetic separation process
PTMS MAGNETIC SEPARATOR
what is magnetic bead separation ?
The structure of the L-type permanent magnet drum-type PTMS electromagnetic separator is characterized by that the magnetic system is composed of ferrite permanent magnets with a covering Angle of 270°, and the polarity of the magnetic poles changes circumferentially. The PTMS electromagnetic separator is divided into two types: single cylinder PTMS magnetic separator band can be adjusted by adjusting the baffle position, and both PTMS magnetic separator can be adjusted by adjusting the magnetic system deflection Angle to meet the needs of different sorting processes. In recent years, dry-type permanent magnet PTMS magnetic separator (magnetic pulley) for dry-type bulk ore has been continuously promoted and applied as an effective equipment for tail-casting in concentrator, playing an important role in saving energy and reducing consumption for customers. Large ore dry type permanent magnet PTMS magnetic separator development soon, equipment technical performance, continuously improve its roller surface points selection of magnetic induction intensity increased from 50 to 180 mT to composite magnetic department of more than 240 mT, full of ndfeb magnets in the department of composite magnetic lump ore dry PTMS magnetic separator roller surface points selection of magnetic induction intensity of 400 mT, highest can amount to 500 mT, and depth of field. The scope of application of bulk ore dry magnetic separator is constantly expanding, and the upper limit of processing size has developed from 75 mm to more than 350mm.
High gradient PTMS magnetic separator is a new type of strong magnetic separator developed on the basis of strong PTMS magnetic separator. In the uniform magnetic field generated by ferro-coated solenoid, polymagnetic media such as steel wool and steel plate mesh are set to generate highly uneven magnetic field on the radial surface. In recent years, PTMS S dry vibration high gradient PTMS magnetic separator is a developing equipment, which is expected to be used for dry separation of fine weak magnetic ore.
PTMS magnetic separator is used in special iron mining areas, which gives PTMS an opportunity to develop in iron ore dressing technology. However, the general survey of magnetic separation technology and magnetic separation equipment, in the basic research is far from enough, mainly in the study of magnetic field characteristics and magnetic circuit structure innovation. PTMS focuses on the high strength and gradient of magnetic fields. The design of magnetic system structure is more important than the selection of high performance (high magnetic energy product) permanent magnet materials. PTMS combines the characteristics of materials to be separated with those of magnetic field to give full play to the rationality of magnetic separation technology and the effectiveness of magnetic separation equipment design.
High separation accuracy, large size, specialization and energy saving of PTMS magnetic separation equipment are the key points of future development trend and market competition. The development of dry separation and permanent magnetization of fine materials will be a development direction in the field of magnetic separation. Meanwhile, the research on magnetic separation technology dominated by multi-field field (wind force, centrifugal force, gravity, electric force, hydraulic force) will also be the key to the development of magnetic separation technology.
