A kind of vertical centrifugal ore selector suitable for iron ore dressing
Technical field
The utility model belongs to a kind of gravity beneficiation equipment, and in particular to a kind of vertical centrifugal ore selector.
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 locating
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:After rotating cylinder in the importing of ore deposit ore pulp, heavy mineral Quick spin is deposited in
The lower half of rotating cylinder, the part in them are moved upward in final election groove, the back-flushing on barrel with centrifugal action
Under effect, mineral are able to loose and selected in groove.Light mineral centrifugal force because suffered by is small, and being flushed outside rotating cylinder turns into mine tailing.Weight
Mineral grain is because by larger centrifugal force, being retained in concentrate bed, 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, in light weight, power consumption is small, easy care, concentration ratio are high, and need not
Medicament adds, to realizing that Green Mine is of great importance.The sorting mode being combined using strong magnetic-centrifugal classification, it 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.
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
Spend 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 in China, and bloodstone
For density far below precious metal minerals such as gold, silver, the charging gear for commonly using vertical centrifugal ore selector is uneven there is cone material feeding is sorted
It is even, advance centrifugal classification can not be shifted to an earlier date, effectively disperse the problems such as 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 defects of middle concentrate grade is low, improve production and technical indication.
The content of the invention
The purpose of this utility model is aiming above shortcomings in the prior art, there is provided one kind can effectively disperse
Ore pulp, the vertical centrifugal ore selector suitable for iron ore dressing for being advantageous to the uniform material feeding of sorting cone, there is advance sorting.
