Abstract
The magnetic separator includes separating ring and magnetic field unit, the magnetic field unit is distributed beside the separating ring to produce magnetic force lines penetrating the separating ring, and the separating ring is provided with at least one pulse device to make ore pulp move in the direction perpendicular to the magnetic force lines. Owing to the combined closed magnetic field unit to produce horizontal magnetic force lines and unique double-pulse device, the particles adsorbed to the surface of the medium exist only in the side in magentic force line direction and the ore pulp reciprocates to produce fluid motion tangent to the particle side and shear and clean the particles, so that the included non-magnetic and weak magnetic adherant particles are washed out resulting in greatly raised separating effect.
Description
Technical field
The present invention relates to the magnetic separator that a kind of ore dressing is used, particularly double-frequency pulse and double-vertical ring high-gradient magnetic separator.
Background technology
The proposition of high-gradient magnetic separation theory gives magnetic separation circle with qualitative leap, and the mineral species that allows to magnetic separation increases, and the granularity upper and lower limit broadens.
Early stage high gradient magnetic separator is a periodic, also claims magnetic filter, and this kind equipment is used widely in handling the occasion that magnetic material content is extremely low and granularity is very thin.
The continuous high gradient magnetic separator of Chu Xianing has the strong magnetic high gradient magnetic separator of the flat ring type of electromagnetism, permanent magnetism and electromagnetism double-vertical ring high-gradient magnetic separator immediately.The electromagnetism horizontal disk high gradient magnetic separator is owing to give the ore deposit identical with the rinse water direction, so cause machinery to stop up easily, the permanent magnetism double-vertical ring high-gradient magnetic separator is owing to the as easy as rolling off a log formation strongly magnetic mineral at the feed port place, the particularly accumulation of iron filings and magnetic takes place stop up, the magnetic separation of electromagnetism vertical ring high-gradient is owing to give the ore deposit opposite with the flow direction of rinse water in media stack, so being not easy to take place machinery stops up, again owing to be electromagnetism, so when exciting curent does not exist, strongly magnetic mineral and iron filings are easy to come off at the feed port place, magnetic is stopped up and is not taken place, and its outer magnetic line of force is parallel with the ore deposit flow path direction beneficial to improving separating effect.
For being mingled with of nonmagnetics in the product that deperms, vibration pulsating high gradient and pulsating high gradient magnetic separator have appearred, as Chinese patent 86106144.6 disclosed a kind of pulsating high gradient magnetic separators, it can make the richness that is recovered material long-pending more a lot of than improving, simultaneously because the panting action of water has reduced mechanical obstruction.But the core work principle of this kind equipment is that to be based upon the pulsation direction of ore pulp or water consistent with magnetic line of force direction, as shown in Figure 6, when the pulsation direction of ore pulp or water is consistent with magnetic line of force direction, the particle swarm that is adsorbed on the dielectric surface only exists along a side of magnetic line of force direction unanimity, at this moment, move back and forth the positive pressure of the fluid force that produces or draw particle swarm by ore pulp, because there is the existence of medium particle swarm front or back, the cushioning effect of its internal liquid, the fluid force that makes is retarded, be unfavorable for the evacuation of particle swarm, the more weak intergrowth of nonmagnetics that is mingled with in the particle swarm and magnetic can not be cleaned out effectively.Therefore, separating effect is more limited, can not take into account concentration ratio and metal recovery rate, output concentrate and tailings, concentrate grade and metal recovery rate can only be protected one, if two all will be protected and will increase by one section operation again, increase investment and operating cost, promptly when obtaining high-grade concentrate, metal loss is bigger in the mine tailing; Otherwise when tailings grade is effectively controlled, the difficult quality guarantee of concentrate.
Summary of the invention
The object of the present invention is to provide a kind of can the output qualified concentrate containing, can keep the rate of recovery again, simultaneously can also output part chats, particularly separate the double-frequency pulse and double-vertical ring high-gradient magnetic separator of the differentiated weak magnetic mineral of two or more magnetic.
Technical scheme of the present invention is achieved in that
A kind of double-frequency pulse and double-vertical ring high-gradient magnetic separator, comprise separation ring, magnetic field device, it is characterized in that magnetic field device is distributed in the separation ring both sides, it can produce the magnetic line of force that runs through separation ring, and described separation ring below is provided with the pulser that at least one cover can make the direction motion that ore pulp produces and the magnetic line of force is perpendicular.
The serve as reasons magnetic confining field device of the produced horizontal magnetic force line that left magnetic pole, right magnetic pole, left yoke, right yoke, preceding yoke, rear magnetic yoke form of described magnetic field device, its magnetic field device background induction is adjustable continuously in the 0-1.3 scope; Above-mentioned left magnetic pole, right magnetic pole are along the left and right curved distribution of sorting ring wall, and the cambered surface cornerite that its relative separation ring axle center forms is 120 °.
Above-mentioned pulser is the dipulse device, comprises dipulse mechanism, mine tailing bucket, middle ore bucket, and wherein dipulse mechanism branch is located at mine tailing, the middle ore bucket outside, links to each other with ground by frame therebetween.Above-mentioned dipulse mechanism comprises motor, reciprocal case and be located at the terminal pad that eardrum is housed of reciprocal case output axle head, and wherein motor is that driven type is connected with reciprocal case, and terminal pad is connected with reciprocal case by being located at the end cap of exporting axle head.Above-mentioned mine tailing pulse mechanism is provided with mechanical pulsing value adjustable in 0～50mm, and its pulse frequency is 0～6.5HZ, and the chats pulse mechanism is provided with mechanical pulsing value adjustable in 0～50mmm, and its pulse frequency is 0～7HZ.
The present invention is owing to adopt magnetic confining field device and unique dipulse device that can produce the horizontal magnetic force line to combine, the fluid dynamic that can produce according to the ore pulp pulsation section different in magnetic separator sorting space with the magnetic force that magnetic field produces is to the difference of the different mineral grain group active force of magnetic, especially when magnetic line of force direction be level and and the ore pulp vibration-direction of pulse generation when perpendicular, the particle that is adsorbed on the dielectric surface only exists along a side of magnetic line of force direction unanimity, at this moment, it is tangent that fluid force direction that move back and forth to be produced by ore pulp and dielectric surface particle swarm are assembled a side, ore pulp just passes particle swarm inside, it is sheared and cleans, the nonmagnetics and the more weak intergrowth particle of magnetic that are mixed in the particle swarm are cleaned out, thereby increase substantially separating effect.The dipulse device can be taken into account concentrate quality and metal recovery rate, can obtain high-grade concentrate, tailings grade is dropped to a certain degree, go back output part chats simultaneously, its chats may be an intergrowth, may be magnetic one or more other mineral between the concentrate and tailings mineral, also may be that the both has.This equipment is particularly suitable for handling and contains the ore that multi mineral that magnetic do not wait is formed, and also is fit to separating and the removal of impurities of nonmetallic ore of simple magnetic and nonmagnetics simultaneously.
