The utility model has the advantages of high magnetic induction intensity and gradient, magnetic field distribution is reasonable, and the energy consumption is low, selects separately effectually, operates steadily, longe-lived.
Description
The utility model relates to dry strong-magnetic separator with inductive roller, is applicable to the separation of particulate weak magnetic mineral, is specially adapted to the purification of industrial mineral.
In the ore dressing practice, much more dry strong-magnetic separator with inductive roller has application, its induction is 1.6～2.0 teslas, generally responds to roller and is formed by silicon steel plate packing, because tooth Profile Machining is difficulty relatively, thereby the magnetic induction gradient is restricted, and induction roller surface modification treatment is difficult to carry out, and silicon steel sheet hardness is low, easy to wear, the cost costliness, the silicon steel sheet demagnetization is slow, makes relatively difficulty of induction roller surface regeneration.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, a kind of high magnetic flux density to be provided, the high magnetic gradient, and the industrial area Distribution of Magnetic Field is reasonable, energy consumption is low, and the sorting refining effect is good, operates steadily the intensity magnetic separator that the life-span is long.
The technical scheme that realizes above-mentioned purpose is: dry strong-magnetic separator with inductive roller, comprise frame, motor, reductor, upper groove body, lower groove, coil system, yoke, cartridge and induction roller, it is characterized in that: upper and lower two the induction rollers of a respectively by means of supporting shaft holder, with the bearing support that is welded on the cartridge side on cartridge, be lined with non-magnetic conduction backing plate between supporting shaft holder and the bearing; B is respectively equipped with the adjustable mine-separating board that is connected on the casing and is fixed on casing both sides and the contacted ore deposit brush that unloads in induction roller surface in upper and lower cell body; C cartridge angle of throat α is 90 °～110 °.
The magnetic conductivity favorable industrial pure iron that the insulating trip that the induction roller adopts segmentation to be provided with insulate is made, and is embedded in key on the stainless steel shaft of non-magnetic conduction.
Owing to adopt technique scheme, compared with the prior art the utility model responds to the magnetic induction intensity height of roller, can reach 2.3 teslas, magnetic induction gradient height, working area field distributes rationally, and energy-saving effect is remarkable, operates steadily, life-span is long, the sorting index height, and overall economic efficiency is good.

Accompanying drawings further describes as follows to the utility model.
Dry strong-magnetic separator with inductive roller, comprise frame (1), motor (3), reductor (4), upper groove body (6), lower groove (2), coil system (5), yoke (7), cartridge (8) (10) and induction roller (11), it is characterized in that upper and lower two induction rollers are respectively by means of supporting shaft holder (19), be bearing on the cartridge (10) with the bearing (20) that is welded on the cartridge side, the induction roller becomes to be arranged vertically on upper and lower two, mineral are carried out twice sorting, strengthen purification, improved the sorting index and the efficient of mineral effectively.Be lined with non-magnetic conduction backing plate (9) between supporting shaft holder and the bearing, with the stainless steel bolt of non-magnetic conduction that it is fastening, reduced the influence of magnetic to bearing, improved condition of work.
In upper groove body, lower groove, be respectively equipped with and be connected the mine-separating board (17) that can carry out adjusting angle on the casing (18) and be fixed on casing both sides and the contacted ore deposit brush (16) that unloads in induction roller surface.Thereby can regulate mine-separating board according to different mineral, and then regulate the PR of magnetic mineral and non magnetic ore.Unload ore deposit brush and can make that to unload the ore deposit abundant, improved the regeneration rate on induction roller surface.The angle of throat α of cartridge (10) is controlled between 90 °～110 °, has reduced leakage field, has increased the space of unloading the mining area.
The magnetic conductivity favorable industrial pure iron (14) that the insulating trip (15) that the induction roller adopts segmentation to be provided with insulate is made, and is embedded in key (13) on the stainless steel shaft (12) of non-magnetic conduction.Groove can be processed in induction roller surface, makes its surface become dentation, and favourable raising induced field intensity and gradient are carried out modification to induction roller surface profile of tooth and handled, and improve its hardness and wearability, have prolonged the service life of induction roller.
When dry strong-magnetic separator with inductive roller is worked, the coil system energising back that is enclosed within on the yoke produces magnetic field, through yoke, induction roller and cartridge form magnetic loop, between induction roller and cartridge, produce induced field, pass through motor, reductor drives the induction roller and rotates, after mineral feed the workspace, the paramagnetism ore particle is magnetized, collecting is on the crown of induction roller surface, along with the induction roller rotates, ore particle enters theoretic zero magnetic area of induction roller, fall into the magnetic product material receiving area of upper groove body at deadweight and centrifugal action, part magnetic ore particle is brushed and is unloaded by unloading the ore deposit, also enters the magnetic product material receiving area, the weak ore particle of non-magnetic ore particle and magnetic pole falls into the non-magnetic product material receiving area of upper groove body at deadweight and centrifugal action, has finished roughly selecting of mineral.
The weak ore particle of nonmagnetic ore particle after roughly selecting and magnetic pole enters the higher following induction roller workspace sorting again of magnetic induction intensity by cell body, be selected or scan, be implemented in and finish two sections on the equipment and sort, reduced auxiliary equipment and floor space, energy-saving effect is remarkable, and overall economic efficiency is good.
