Description
Technical field
The utility model 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
