Description
Technical field
The present invention relates to a kind of ore dressing screening installation, particularly a kind of new bifurcated spiral chute.
Background technology
Utilization is continually developed with non-renewable mineral resources, abundant ore source is increasingly deficient, under head grade continues
Drop, is constantly risen for the refractory ore proportion of outstanding feature with poor, thin, miscellaneous, causes conventional beneficiation method and equipment to exist
Technology and economically face a severe challenge.
Spiral mineral is one of a kind of simple, energy-conservation and efficient beneficiation method.Wherein typical equipment is spiral chute,
Its body of work part is a spiral shape chute, and its operation principle and process are：Ore pulp is fed from top, is flowed over along groove
It is layered in journey, the heavy suite into bottom is intended to the inner edge motion of inside groove, and light mineral is then in quick revolution fortune
Outer rim is thrown toward in dynamic, by the difference of grain density, mineral sort band in the horizontal spreading of groove.But at present, with ore grinding
The reduction of granularity, the decline of particle specific gravity differential effect so that spiral mineral has many in terms of the sorting of fine grained mineral
Problem, as fine grained valuable mineral is easily mixed into tailing zone, separating effect is poor, causes the decline of concentrate grade, under concentration ratio
Drop, the raising of tailings grade, decline of the rate of recovery etc..
The content of the invention
Technical problem：It is an object of the invention to provide a kind of new bifurcated spiral chute, raw ore can be thrown in advance
Tail and further selected, so as to effectively improve the efficiency of separation, improves concentrate grade and the rate of recovery, and then solve the above-mentioned back of the body
The problem of being proposed in scape technology.
A kind of new bifurcated spiral chute provided by the invention includes material bin, principal screw chute, two bifurcated spirals and slipped
Groove, sparge pipe, bifurcated baffle plate, three newels, baffle plate, column base, base, newel and discharge gate are formed, three column bases
On base, three newels are separately mounted on three column bases, and principal screw chute is arranged on middle newel, and two
Individual bifurcated spiral chute is arranged on the newel on both sides, and sparge pipe is arranged at the pan feeding of bifurcated spiral chute, three discharges
Mouth is arranged on the lower end of principal screw chute and two bifurcated spiral chutes, and three baffle plates are arranged on principal screw chute and two bifurcateds
On the discharge gate of spiral chute, two bifurcated baffle plates are separately mounted to the connection of principal screw chute and two bifurcated spiral chutes
Place, material bin are arranged at the top feed of principal screw chute.
The pitch of principal screw chute and two bifurcated spiral chutes can be according to reality in the new bifurcated spiral chute
The needs of mineral continue to calculate, design and adjust.
Advantages of the present invention shows the following aspects：
1. the structure of this new bifurcated spiral chute is simple, good separation effect, the efficiency of separation of the fine-particle minerals of raising.
2. 1. a new bifurcated spiral chute can be thrown tail in advance by bifurcated spiral chute to raw ore, spiral below is reduced
The sorting pressure of chute, it also avoid fine grain gangue mineral and be mixed into concentrate.
3. 2. a new bifurcated spiral chute can carry out shunting sorting by bifurcated spiral chute to the chats in rough concentrate, keep away
Exempt from fine grain chats to be mixed into concentrate, improve the grade of principal screw chute product concentrate.
4. a new bifurcated spiral chute finally gives six products, mine tailing 1., mine tailing 2., concentrate 1., concentrate 2., chats 1. and
2. chats, may finally need to carry out reasonably combined according to user, meet market demands.
5. a new bifurcated spiral chute can be actually needed regulation pitch according to different minerals species, spiral chute is improved
To the adaptability of variety classes mineral.
