Utility model content
The purpose of this utility model be to provide a kind of energy-efficient high throughput without eddy-current loss magnetic grader, the problem such as the service life that solved that existing magnetic separating machine barrel skin is easy to wear, cylindrical shell heating causes is short, and equipment is fragile.Its structural design is ingenious, has the advantages such as long service life, simple to operate, treating capacity is large, power consumption is little, maintenance cost is low.
The purpose of this utility model is achieved in that this comprises upper box, lower box, permanent magnetism cylindrical shell, feeding-distribution device, the drive motors with charging aperture without eddy-current loss magnetic grader, it is characterized in that: described permanent magnetism cylindrical shell is made by fiberglass, lower box bottom is W shape structure, two footing of W shape structure are respectively mine tailing mouth and concentrate mouth, permanent magnetism cylindrical shell is arranged between upper box and lower box, and permanent magnetism cylindrical shell bottom is provided with the feeding-distribution device between mine tailing mouth and concentrate mouth; The interior spacing main shaft that has of permanent magnetism cylindrical shell, main shaft is provided with not with the magnetic system of permanent magnetism cylindrical shell rotation, and main shaft is provided with retainer ring, and pipe magnetic separator end of body is arranged on retainer ring, and the main shaft in permanent magnetism cylindrical shell is connected with the output shaft of drive motors; Upper box top is provided with the distribution device corresponding with charging aperture.
The outer surface of described permanent magnetism cylindrical shell is provided with wear and shock-resistant potsherd.
The disk pack angle that described magnetic is is 160-240 °.
Described fiberglass is perspex steel or FRIM.
The advantage the utlity model has and positive technique effect are: utilize to strengthen modified glass steel well mechanical performance replace steel, utilize the characteristic of fiberglass high resistivity simultaneously, while having avoided cylindrical shell operation, cutting magnetic line and the vortex phenomenon that produces.Fiber reinforced plastic barrel end face adopts progressive thickness design, and is provided with retainer ring with the rigidity of reinforced tube.Drum surface adopts wear and shock-resistant potsherd as protective layer, has extended the service life of equipment.The structural design that has adopted little magnetic pole, large disk pack angle, high gradient, improves treating capacity.Be used in conjunction with and there is good sorting result with equipment in small, broken bits such as high pressure rod mill, hammer mills, process the following fine ore effect of 5mm better, concentration ratio is 1.5～3 times of general expression dry-dressing machine, treating capacity increases more than 30%, transmission power reduces more than 50%, extend service life, reached as high as 10 years.Equipment is in service without vortex phenomenon, can realize thick, the selected operation of strongly magnetic mineral dry type, Novel structure makes total heavy burden reduce more than 30%, simultaneously through on-the-spot test, eddy-current loss is 0 substantially, more than can saving electricity 100000 degree separate unit year, treating capacity can increase more than 240000 tons, and application space is huge.The utlity model has in sum structural design ingenious, there is the advantages such as long service life, simple to operate, treating capacity is large, power consumption is little, maintenance cost is low.
