Abstract
The utility model relates to an ore concentrating machine of gold and can increase the recovery of fine gold granules and micro-fine gold granules, and the utility model is provided with no strict requirements to selected mineral granularity. A centrifugal chute rotary drum of the utility model is a horizontal outer cylinder rotary drum and an inner truncated cone rotary drum, an inner wall of an inner rotary drum is distributed with spacer bars, ore pulp can form stable centrifugal flow film bed layer on an inner wall in the rotary drum for the density separation of the mineral. The pulse pressure water injected into the chute rotary drum via a hollow shaft can loosen mineral bed layers on an inner rotary drum wall via the apertures on the inner rotary drum, so the bed layer can be avoided from hardening, and the utility model can strength the density separation of the mineral bed layer.
Description
The utility model relates to a kind of gold ore machinery, and it is a kind of metal recovery rate that can not only improve the gold dust ore dressing; And can improve rock gold mine ore after grinding wherein particulate and the chute gold classifier of microfine monomer gold recovery.
At present, the gravity beneficiation equipment of gold rock gold mine is lower less than the rate of recovery of the fine grained gold of 0.05mm to granularity, and is especially lower less than the rate of recovery of the micro-fine-grained gold of 0.02mm to granularity.At the gravity chute of usefulness, because in gravitational field, acceleration of gravity is definite value, has limited the gravity and the sinking speed of particle, so the disposal ability of equipment is difficult to improve, and reclaims the metal granularity and is difficult to reduce at present; Present centrifugal chute then because the bed of its centrifugal stream film bottom is loose insufficient, is prone to " hardening " phenomenon, causes metal loss and reduce the disposal ability of equipment.The utility model-fluctuation centrifugal chute gold classifier has overcome the defective of above equipment.
The purpose of this utility model is a kind of gold classifier, and it can not only reclaim the coarse granule gold, and can improve the rate of recovery of particulate and microfine monomer gold.
The purpose of this utility model is achieved in that a kind of chute gold classifier, by advancing pipe 9, horizontal centrifugal chute rotating cylinder 2, hollow shaft 4, pulse pressure water feed feeder 5, debris tube 1, bearing block 10,11, transmission device 6, compositions such as water inlet pipe 7 and frame 8.It is characterized in that: horizontal centrifugal chute rotating cylinder 2 is made of distribution parting bead on an outside cylinder rotating cylinder and the inwall and the interior truncated cone rotating cylinder 3 that is drilled with aperture; Cylinder rotating cylinder and hollow shaft 4 join outside the horizontal centrifugal chute rotating cylinder 2, and pulse pressure water waterworks 5 are housed on the hollow shaft 4.Described gold classifier, its centrifugal chute rotating cylinder 2 is horizontal.Described gold classifier, the parting bead that distributes on the truncated cone rotating cylinder 3 within its horizontal centrifugal chute rotating cylinder 2, interior truncated cone rotating cylinder 3 is drilled with aperture.
Sort the mineral granularity lower limit because employing such scheme, the utility model one fluctuation centrifugal chute gold classifier can reduce greatly, improve ore dressing disposal ability and metal recovery rate.
Accompanying drawing is a fluctuation centrifugal chute gold classifier structural scheme of mechanism
Below in conjunction with drawings and Examples the utility model is further specified: certain particle size contain the gold mineral slurry, (interior rotating cylinder 3 is truncated cone shape to inject rotating cylinder 3 within the horizontal chute rotating cylinder 2, inner wall surface thereof is pressed baffled parting bead of certain distance and wall distribution aperture) bottom, ore pulp is under the action of centrifugal force of interior rotating cylinder 3, immediately on the wall attached to interior rotating cylinder 3, and when doing gyration with interior rotating cylinder 3, mobile along the axial gradient of barrel, constitute the spiralling track in the space.Mineral by density stratification at ore pulp with respect to the moving generation of tube surface current, action principle is identical with film concentration in the gravitational field, heavy mineral deposits to the barrel bottom, light mineral is discharged by truncated cone inner core 3 big ends with ore pulp on the upper strata.Meanwhile, the fluctuation pressure water in the chute rotating cylinder 2 between outer rotaring tube is undertaken loose by the heavy mineral bed on the internal tube wall surface in hole on interior truncated cone rotating cylinder 3 walls, avoid bed to harden, and strengthens the mineral bed density simultaneously and separates, and improves the concentrate concentration ratio.
In the accompanying drawings, the chute rotating cylinder of centrifugal chute gold classifier is made up of horizontal outside cylinder rotating cylinder 2 and interior truncated cone rotating cylinder 3.Truncated cone rotating cylinder 3 cone angles in it＜45 °, and certain distance is established a baffle plate parting bead on interior truncated cone rotating cylinder 3 walls, is drilled with aperture on interior truncated cone rotating cylinder 3 walls.Interior truncated cone rotating cylinder 3 needs to make of high-abrasive material.
In the accompanying drawings, hollow shaft 4 is equipped with a pulsating water feed feeder 5, and these pulsating water feed feeder 5 feedwater minimum pressures are lower than the mineral gangue at interior truncated cone shape rotating cylinder 3 maximum radius place centrifugal pressures, but are higher than the mineral gangue at interior truncated cone shape rotating cylinder 3 least radius place centrifugal pressures.
Claims (3)
