The magnetic field force that the utility model utilizes permanent magnetic system to produce, strongly magnetic mineral in the mineral is adsorbed onto on the permanent-magnetic cylindrical outer surface, and along with the rotation of tube skin, after breaking away from the magnetic field force effect, under the effect of scraper plate, break away from tube skin outer surface, outside the discharge machine, the non-magnetic material that is not attracted is discharged from the mine tailing mouth, finishes separation operation.
Permanent magnetic system is a key of the present utility model, the magnetic pole group is extremely wide in the magnetic system, circumferencial direction magnetic pole group quantity, the disk pack angle directly influences the sorting index of equipment itself, the disk pack angle that the utility model adopts is between 120～140 °, correspondence sorts strip length and can reach between 1700～1800m with it, more traditional maximum specification diameter is that sorting of 1200mm permanent-magnet drum type magnetic separator is with and the sorting time has increased by 40～50%, the number of magnetic poles that sorts the band circumferencial direction simultaneously is 7～14, it is that the upset number of times that produces increases that magnetic mineral moves to another magnetic pole from a magnetic pole, concentrate be mingled be improved significantly, concentrate grade is higher; Scanning district's magnet pole widths is 255mm, this magnetic field, place useful effect degree of depth can reach 90～110mm, more traditional maximum specification diameter is that the 1200mm permanent-magnet drum type magnetic separator useful effect degree of depth has increased by 60%, the increase of the useful effect degree of depth has realized the increase of axial unit length treating capacity, maximum amplification can reach 110%, and the rate of recovery of equipment itself also is improved simultaneously.The delivery area and unload the mining area magnet pole widths can be according to characteristics such as material fineness configurations 170mm, 130mm, 100mm.
The tradition permanent-magnet drum type magnetic separator all adopts flushing water to unload the ore deposit, causes concentrate concentration on the low side, and for follow-up technology causes bigger inconvenience, the utility model adopts scraper plate to unload the ore deposit, need not add flushing water, and concentrate concentration significantly improves, and has realized the effect of saving water and energy.
Magnetic mineral is mingled with non magnetic ore when being adsorbed onto drum surface phenomenon is comparatively obvious, directly influences the concentrate index, increases the current flushing after magnetic mineral breaks away from ore pulp, can effectively eliminate the phenomenon that is mingled with of magnetic mineral.
District's magnetic field useful effect degree of depth is scanned by magnetic system can reach 100mm, and it is big that the axial unit length of permanent-magnetic cylindrical is handled energy, magnetic mineral rate of recovery height.Concentrate unloads the ore deposit and adopts scraper plate to unload the ore deposit, and more traditional flushing water unloads the ore deposit mode, and to compare water-saving result remarkable.Rinsing device is set concentrate is washed, further remove concentrate and be mingled with.These facility have the energy of processing, and (axially the unit length maximum can reach 230m greatly
3/ hm), and good separation effect, the concentrate grade height, rate of recovery height, water saving, simple in structure, easy to maintenance, characteristics such as long service life.
