Description
Technical field
The invention belongs to a kind of gravity beneficiation equipment, and in particular to a kind of vertical centrifugal ore selector, available for gold, silver, platinum
The ore-dressing practice of the non-ferrous metal such as the noble metals such as race and tungsten, tin, lead, zinc, for the extensive of iron ore, serialization sorting particularly
It is applicable.
Background technology
Common water-jacket typ automatic centrifugation ore separators is the enhanced special gravity ore deposit equipment based on centrifugal principle, is generally used for place
Manage and the noble metals such as gold, silver, platinum family and the metalliferous mineral of other greater densities are reclaimed from ore, be gold, noble metal association
The conventional gravitational separation equipment of non-ferrous metal ore factory.
Vertical centrifugal ore selector grading principle is：Imported to ore deposit ore pulp after interior rotating cylinder, heavy mineral Quick spin is deposited in
The lower half of rotating cylinder, the part in them is moved upward in final election groove with centrifugal action, the back-flushing on barrel
Under effect, mineral are able to loose and selected in groove.Light mineral is small because of suffered centrifugal force, and being flushed outside rotating cylinder turns into mine tailing.Weight
Mineral grain is because by larger centrifugal force, being retained in concentrate bed, and its concentrate discharging modes is divided into interruption ore discharge and continuously may be used again
Become ore discharge.
Vertical centrifugal ore selector has the advantages that small volume, small lightweight, power consumption, easy care, concentration ratio are high, and need not
Medicament is added, to realizing that Green Mine is of great importance.The sorting mode being combined using strong magnetic-centrifugal classification, is to solve
The effective way of the refractory hematite utilization of resources.Vertical centrifugal ore selector can be effectively reduced the lower limit of gravity treatment granularity, promote
The recovery of Separate Fine-grained Minerals and the comprehensive utilization of mine tailing.
At present, the mine-feeding equipment of vertical centrifugal ore selector is made up of a mineral-feeding pipe and circular flat pallet, mineral-feeding pipe end
There is taper closing in, because the density variation of these mineral is larger, main sorting is tapered sleeve part, is selected using conventional vertical centrifugal
The charging gear of ore deposit machine.
In the past more than ten years, the batch centrifugal ore separators gold at home developed according to gravity separation principle design
Mine is widely applied.《Gold》" the STL series Water sleeve centrifugal ore sorting R ＆ D designs that 7th periodical in 2016 is delivered
And application " in a text, introduce the current situation of the serial Water sleeve centrifugal ore sortings of STL, including R ＆ D of complex, product are set
Meter is with verifying, product improvement front-end geometry is selected one kind backwash continuous centrifugal when technological parameter, and person with application
The structure and working method of ore deposit machine are studied and designed, but not industrially successful Application up to now.
Along with the continuous reduction of rich ore and easy quarry, the grade of ore in part mine declines year by year, the embedding cloth grain of mineral
Degree is superfine.Vertical centrifugal ore dressing is especially sorted by the research and attention of more ore dressing researchers in microfine iron ore concentrate
In terms of the recovery for bloodstone in iron tailings, some Science Explorations and Primary Study have been done.
Refractory hematite reserves account for the 1/3 of national gross reserves in the explored iron ore deposit of China, and bloodstone
Density has sorting cone material feeding inequality far below the precious metal minerals such as gold, silver, the charging gear of conventional vertical centrifugal ore selector
It is even, it is impossible to shift to an earlier date the problems such as advance centrifugal classification, effectively scattered ore pulp, cause the concentrate grade in hematite separation low, therefore,
Must the charging gear of vertical centrifugal ore separator be improved, preselect in advance as far as possible, so as to effectively solve hematite separation
The low defect of middle concentrate grade, improves production and technical indication.
The content of the invention
The purpose of the present invention can effectively disperse ore deposit aiming above shortcomings in the prior art there is provided one kind
Starch, be conducive to the uniform material feeding of sorting cone, the vertical centrifugal ore selector with advance sorting.
To realize the above-mentioned purpose of the present invention, a kind of vertical centrifugal ore selector with advance sorting of the present invention is used
Following technical scheme：
A kind of vertical centrifugal ore selector with advance sorting of the present invention is by charging gear, rotation sorting discharge cone
