Technical field
The utility model belongs to a kind of gravity beneficiation equipment, and in particular to a kind of vertical centrifugal ore selector, water is replaced with it
Shell type automatic centrifugation ore separators, the continuous ore discharge of vertical centrifugal ore selector can be achieved.
Background technology
Vertical centrifugal ore selector is the general designation of rotary shaft right angle setting centrifugal ore separator, and operation principle is the driving in motor
Under, cone cylinder is rotated by pulley drive, drives the ore pulp in cone cylinder to rotate at a high speed, in the process, based on different densities
The difference of centrifugal force suffered by particle, different densities particle realize separation under centrifugal sedimentation and stream film turbulent diffusion.
Vertical centrifugal ore selector, including external Knelson (Nelson) centrifugal ore separators and Falcon (Fa Erkang) from
Heart ore separators and domestic Water sleeve centrifugal ore sorting, for the enrichment of the mineral such as chromite, ilmenite, Iron Oxide Minerals, tool
There is ratio of concentration height, treating capacity is big, floor space is small, assorting room is fast and effective, device structure is simple, production cost is low, to ring
The advantages that border close friend.And do not limited by grain graininess, greatly reduce the granularity lower limit of recyclable mineral so that submicron-sized particulate
Gravity separation be possibly realized, in addition, it is not necessary that medicament add, because the discharge of mine tailing and the purification of waste are simplified, not only
Production cost is reduced, and reduces Environmental costs.Vertical centrifugal ore selector is increasingly by the weight of ore dressing researcher
Depending on.
But it is architectural limitation to be applied to industrial most of vertical centrifugal ore selectors at present, can only be interrupted discharge essence
Ore deposit, it is impossible to work continuously, therefore be basically applied to the noble metals such as the few gold, silver of concentrate quantum of output, platinum family and tungsten, tin, lead, zinc
Deng the ore-dressing practice of non-ferrous metal.
The content of the invention
The purpose of this utility model is aiming above shortcomings in the prior art, there is provided one kind has automatic discharging

15~30mm.
A kind of continuous vertical centrifugal ore separator of the utility model, after ore pulp feeds flat pallet by mineral-feeding pipe, ore pulp exists
Sorting discharge cone medial wall of the tube is thrown toward in the presence of centrifugal force, groove is crossed and gradually moves upwards.Pressure flushing water in water jacket
It is injected into through aperture in sorting discharging cone cylinder, under the collective effect of centrifugal force and recoil waterpower, thin weight particle is easy to sink to groove
In ditch, imported through concentrate ore discharge pipe in concentrate hopper;And gangue and light mineral particle, it is smaller by centrifugal force, in buoyancy and ascending water
Flow under impulse force, constantly taken away by back-flushing, overflowed and arranged to tail-box from sorting discharging cone cylinder top overfall, turn into mine tailing, from
And realize mineral and sorted by grain density.
A kind of continuous vertical centrifugal ore separator of the utility model is after adopting the above technical scheme, with following actively effect
