Abstract
A high efficiency screw chute is used for mineral concentration. The present spiral chute is imparted in raw ore form the upper part of spiral chute, and concentrate and tailings are expelled from the lower part of the spiral chute. The separation effect is poor without getting high grade concentrate and recovery rate. Usually, the high grade concentrate can be yielded on the second segment. Mineral substance need transport pump to be transported from the first segment to the second segment with larger energy consuming. The arranged equipment in the utility model adds a tailing device and a hydrophone, which can get the high grade clean ore at the first segment The work recovery rate increases 4%-5%.
Description
A kind of gravitational separation equipment that is used for ore dressing.
The spiral chute of using is to feed raw ore from the upper end spiral chute at present, and the lower end picks out concentrate and tailings (chats, mine tailing, Bian Kuang).When the stream of mineral film moves to a constant pitch, just begin to make concentrate, middle band serious dehydration, do not reach thoroughly and make, press proportion and granularity layering more effectively and divide band, so one section spiral chute is reached than high-grade concentrate and rate of recovery higher efficacy at one section spiral chute; In addition, tailing zone, limit tail band are subjected to gyration and the intrusion concentrate band that recoils, make concentrate band and middle band be subjected to the overlapping pressure to the inner edge extruding of above two bands, so the separating effect ability drop, also transport with pump by one section to two sections need, so power consumption is bigger owing to on-stream.
The purpose of this utility model is that a kind of high-effect spiral chute will be provided, and it not only can one section just sub-elects qualified concentrate containing, and concentrate grade and operation recovery all be higher than the index of original equipment, energy savings, and equipment is simple, saves a large amount of investments.
Invention is achieved in that
On this equipment, installed additional and section gone out (mine tailing, the limit tail) mine tailing device (2) and add hydrophone (3), so when mineral after spiral lower end flows LAP, ore deposit, part limit and mine tailing just flow in this equipment true tailings and go along cutting mine tailing device (2), thereby reduced mine tailing, the concentrate band of limit Caudad spiral chute inner edge and the overlapping pressure of invading extruding of middle band, lean on the concentrate band of spiral chute inner edge, middle band seriously forms dewatering state, add hydrophone (3) this moment and inject the current of adding that form a certain angle with the stream of mineral film, concentrate and middle band have been cleaned so once more, thereby improve concentrate purity, reduced mine tailing again.Spiral chute sorting usefulness has improved like this, has not only improved concentrate grade but also reduced tailings grade.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
The high-effect spiral chute structural representation of Fig. 1
The drawing explanation: spiral chute (1), cut (mine tailing, limit tail) mine tailing device (2), add hydrophone (3).
Embodiment and operational detail are described in detail in detail in conjunction with the accompanying drawings:
High-effect spiral chute is cut (mine tailing, limit tail) mine tailing device (2) and is added hydrophone (3) formation by spiral chute (1).Cut (mine tailing, limit tail) mine tailing device (2) and add hydrophone (3) and all be installed on the spiral chute.Cut (mine tailing, limit tail) mine tailing device (2) and be spiral chute in flow process, wherein a part of mine tailing and limit tail are cut out, mix, finish this operation and all work with this group spiral chute true tailings; Adding hydrophone (3) is to inject the current of adding that form a certain angle with the stream of mineral film.
Embodiment:
Use high-effect spiral chute on iron ore, sort for one section through this spiral chute, make concentrate reach iron content 65-66% grade, this operation recovery is brought up to 35-40% by original 31-34%, and operation recovery improves 4-5%.
Claims (1)
1, a kind of spiral chute that is used for ore dressing, feature of the present utility model is high-effect spiral chute, installs additional to cut (mine tailing, limit tail) mine tailing device (2) and add hydrophone (3) on spiral chute (1).
