iijiios Thunder for mineral processing.

The utility model relates to the mining industry, in particular, to the enrichment of minerals by gravitational methods and can be used to extract BVN .. industrial and native metals in the separation of metal-bearing sands and conglomerates.

A known flushing device including a head airlock and a screen located beneath it, connected to a chute with a estrus with a curved surface, having a mechanism for regulating their inclination, as well as irrigation devices, while sifting the screen:; The screen of the crash is connected to the lower end face

/ see, for example, the description of the invention to the patent of the USSR I 1776k: 01, cl. li 03B 5/70, lS92r./.

A disadvantage of the known utility lies in the efficiency of enriching difficult-to-recover classes due to the impossibility of regulating the flow hydrodynamics at the gateways.

the closest possible result known from its technical essence .. the result is a gateway screen for mineral processing selected as a prototype, containing the main ceKHiiM in the form of a gutter with a swinging stencil and a bottom inclined in the longitudinal direction articulated under a stencil1U1I and equipped with % .: with a device for regulating its inclination, a suspended lapping gateway and a side tapering trough

In the process of exploitation, large grains settle in the cells of the trad.) And of the Uets and form a bed through which the heavy Janerales penetrate; The fact is that the finer: 1st particles 1: of the genals from the base Jij / i are not continuously removed, there is a gradual continuous, more and more quieter, the capturing process practically stops and sharply shrinks the extracted melm1X metal particles.

The essence of the claimed useful product is expressed in the combination of essential features sufficient to achieve the desired technical model provided by the proposed useful model, which consists in increasing the work efficiency by regulating the technological process of enrichment.

The claimed combination of essential features is in direct causal relationship to the specified technical res; ult.

the breechness of the proposed device is seen in the fact that the COCTOJ / LT suspension lapping gateway is made up of the head and lapping sections with a system of lateral swinging, stencils pivotally connected by means of an adjustable link, and the lapping section is equipped with a hopper for collecting the undergrate product, while the hopper is equipped with a nozzle for supplying water under excess pressure.

Comparing the first claimed technical solution with npoTOTj inoM allowed us to establish its criterion and novelty, as it is not known from the prior art.

The proposed ycT, jOECTBo can be repeatedly played back with existing tech2; chesky1y1u: And the means, because The content is ivi-building 5 halls and elements i meets the criterion of industrial prolesity.

laKifiM in the manner proposed .. the property is consistent with the installed /. patentability criteria of a utility model.

No other well-known technical solutions of a similar designation have been found by the applicant with similar essential features.

The essence of the claimed utility model is illustrated by the attached 1i1 and drawings, on which

a sluice-rumble was given for the enrichment of minerals, npej / iiviymeoTBeHHO metal-bearing sands, sand and pebble ivaTepj ajia pulp, and containing the main section in the form of a rectangular groove 1 with a system of transverse swinging-gypsy stencils 2 installed with a technological gap of 6. one from the other. Stencils 2 through the guide 3 are connected with the crank 4 of the eccentric drive 5.

The screening gateway contains a hanging latching gateway 6, a lateral tapering groove 7 and a longitudinally inclined bottom 8, pivotally mounted under the stencils 2, equipped with a device e;

The screening gateway is equipped with 6yHKej..oM S for collecting the undersized product.

The lateral tapering groove 7 is provided with a flow rate divider for flowing material / not conventionally shown /. In the tail part of the gutter 7, there is a direct 1st zug-shf 10 for collecting concentrate.

Suspended latching gateway 6 consists of several GC, one imer, head 11 / zone KOHLTeHTj..auxni / and lapping 12 / zone water: J / x gravity concentrate / secpia with transverse swinging stencils, w; articulated through an adjustable compensation link; in the screw coupler 13, while the hopper S for the mixed product is placed under the finishing 12 sepia and is equipped with nozzles 14 for supplying water under excessive pressure and removing the subfacial fraction.

The concentration zone is a system of pipes with swinging stencils, similar to the design of the main section 1, installed with a technological gap of 2-3 b from the fixed bottom.

The work of the proposed ystJ.; Property is carried out as follows,

The source material in the form of pulp enters the rectangular groove 1, spreading out over its entire width. Incoming products in the swinging stencil area 2 are classified according to KpynnocTii and enriched. Swinging movable Tpa4) ajjeTOB provide loosening of mineral

 6 fe 6 to

the bed is provided with a plank of stencils, which contributes to the cerperaiMii, which is smaller, the afmsaji class is 5 mm with the simultaneous concentration of the useful component in small frashzhzh.

Depending on the required quality and volume of the continuously emitted under-sieve product, the gap between the main seksha 1 k inclined bottom 8 is regulated until the supply of the fine fraction to the under-sieve product is completely stopped ;; t.

Through branch 15, the under-sieve fraction enters the suspension lapping gateway 6 for the subsequent enrichment of the suspension su; d 1 in one trough 7 for decontamination.

Lattice product with a particle size of more than b mm is discharged by flow energy into the dump.

The enriched sterial with a particle size of up to 5 nm continuously discharged; ; shrinks through technological gaps between the swing; syafa ,.) 2 and through the discharge windows / not shown / enters the suspension lapping gateway 6 for subsequent enrichment or suspension sow; brewing channel 7 for dehydration. The amount of undersized material is regulated by means of a pivotally secured inclined bottom 8, which provides back pressure along its entire length.

When swinging stencils move, the mineral bed on the bottom is constantly loosening, heavy generals, due to their high density and under the influence of segregation, penetrate into the lower layers of the material and are retained in it, and light minerals are carried away to the tails.

The water supplied to the bunker under excess pressure helps to maintain the settled layer in a suspended state and expelled by more light and small particles into a separate stream, washing out the ballast from it, including them. The concentrate accumulates in the part of the hopper and, when rinsed through the outlet, is unloaded into special containers for shipment to the concentration plant.

h

in Bej xHiix layers, dominant particles are lower particles of lower density Tii, and in HiiXHiuX, higher densities. Along with different speeds of the moving H / iH layers of material along the height of the tapering stream, it contributes to the separation of the layers of the stream at the exit of the gutter. The decomposition of the crust of crustentrate is carried out by cutting off the nth prR1 bottom layer in the flow fan. Condensed with a solid to liquid ratio of 1: 3 - 1: 5, it is sent to an intake sump 10, from which it is fed to a centrifugal concentrator (not shown) / subsequent enrichment by means of an electric pump unit. The drain from the hitch / w enters the dump.

The application of the proposed lock-screen increases the efficiency of the flow separation and the extracted small classes of the foam component, while increasing productivity and production as a whole.
