Operation principle and the process of centrifugal oscillating-table-type gravity separator for fine particles of the present invention are as follows:
Selected material to feed according to the concentration ratio of the mineral regulations top by ore pulp pipe; material drops on the pulp distributer by carrying out unlatching ore pulp magnetic valve Vertical Free along ore pulp pipe; the material of vertical drop obtains one to the initial velocity that moves slightly on the upper side all around; on the basis of this initial velocity; the centrifugal force that pulp distributer rotation produces makes and feeds material and get rid of to the circumferencial direction of separator plate quickly and evenly; the heavy metallic mineral particle that proportion is larger obtains larger centrifugal force; under the huge gravitational field effect up to 500Gs～600Gs; mineral are according to minute constituency fast hierarchical of different separately proportion along separator plate, and the heavy metallic mineral particle that proportion is larger arrives minute collecting region of top, constituency and rests in the compartment of adjustable lip glazing bar.Within the whole service cycle, signal power source from programmable PLC automatic system device is controlled stepper motor work by the holding wire of MXP rotaing contactor, thereby promoting to regulate support ceaselessly moves inward the flexible tongue piece in the adjustable lip glazing bar, so that being provided, sufficient space collects target mineral-concentrate, simultaneously from PLC automatic system device control signal source control dc speed-regulating motor, dc speed-regulating motor is by reciprocal differential gear, connecting rod and adjusting support drive separator plate and do reciprocal differential swing take its center of circle as axle, form the how sharp field of force, even under up to the huge gravitational field effect more than the 500Gs, still can keep laminar shear, disperse, layering with separate, prevent that enrichment region has layer by layer compacting knot tying phenomenon in the compartment, thereby realize the effective sorting of fine-particle minerals.Because being back taper, arranges each compartment of the lip glazing bar of the fan-shaped sorting face of separator plate again; therefore up the linear velocity of each compartment increases gradually from pulp distributer; the centrifugal force that mineral grain in its relevant position obtains is also larger; so produce a motion component that makes progress; this component impels useless light mineral to be got rid of by throwing to the mine tailing chute through downflow weir, discharges through the mine tailing ejection nozzle.According to the programme-control requirement, at regular intervals, the operation of machine automatic slowly, under the help of PLC procedure auto-control device, opening high pressure jet water spout magnetic valve is got concentrate express developed, concentrate flow into the concentrate chute and through the discharge of concentrate ejection nozzle, finishes one-period operation work through ejaculation pipe magnetic valve, then carries out again and again next cycle operation work.
Outstanding advantages of the present invention is:
1, can be widely used in vein ore deposit, the placer of various precious metals, the sorting of mine tailing is reclaimed, and has the ultra tiny particle diameter useful component of superpower collecting.The collecting grade is below-200 orders, can realize reclaiming useful composition and precious metal to the mine tailing that abandoned in the past again.Its recyclability and concentration ratio are high, and concentration ratio is minimum to be reached more than 1000: 1.
2, because the reciprocal differential swing of separator plate forms the unique design in the multiple field of force and the space controlled architecture of collecting region, compacting knot tying phenomenon is arranged when having overcome the centrifuge ore dressing, make it when processing the microfine sludge, roughly select and once can abandon 85～90% secondary mine tailings.
3, this equipment has also adopted programmable PLC automatic control system device, makes it when sorting different minerals, adjusts centrifugal rotational speed, feed flow, feedwater, concentrate flushing operation very convenient.
