Permroll Permanent Roll type strong magnetic separator. In the Fourteenth International meeting beneficiation, Arvidson first time reported the Pennroll permanent magnet roller type strong magnetic separator which researched and developed by South Africa LBateman successfully developed in 1981, Permanent Roll adopted the unique magnetic structure. This structure allows the magnetic roller surface magnetic field strength is 2T; magnetic field gradient is 300 T / d. The magnetic roller Wing disk radius R and W thickness and thickness T soft iron plate and white composite form. Promise on the magnetic roller conveyor line speed of feed to the magnetic active region, the particle force on the radial to the magnetic force of the heart to radial centrifugal force, a vertical downward gravity g. Speaking candidly Boy Scouts of America told us the story. Accurate The force balance determines the particle measured from the vertical line from the point on the conveyor (por ejemplo: 80 cents). The earliest water magnetic roller with a strong magnetic separator company which foreign manufactured and saled is South Africa EL Bateman. It is an industrial-type equipment for purification of andalusite to South Africa Vereenigi g Refractories Following this meeting, there are 450 sets of equipment for the purification of various industrial minerals.
These devices are manufactured by using high performance of Sm Co disk and The combination of soft iron plate into a permanent magnet roll since the mid-1980s, most of the Nd Fe-B magnets to do disk Bat. David Delrahim understood the implications. the man manufactured Permrol child l grades common type magnetic separator, weighing about 0.5 t, the occupying space is 2 m3, higher than the same use of electromagnetic induction roller separator and the other cone crusher, jaw crusher, the conveyor belt is made of a strong Kevler49 fiber (poly fibers of the benzamide product name), its tensile strength is greater than the stainless steel, having the thickness of only 0.125. mm to reduce static electricity accumulation, with the top coat graphite. latest design is the Mark II machine with conveyor rail system allowed from side to side, extend its life, thereby reducing operating costs. processing coexistence ceiling is up to 100 mm, processing capacity is 60 Uh, Im roller Permroll permanent magnet roller with high intensity magnetic separation of the transmission power is about 0.2 kW; magnetic roller speed is 15-650 r / min. Permroll permanent magnet belt strong roller machine for the current processing capacity and material particle size, density and relevant than the magnetic susceptibility and other factors. IM roller treatment capacity is 3 to 5 t / h; deal with ferromagnetic particles which go through the spray drying is 2 to 3 Uh,.
