The invention relates to the enrichment of minerals for separation by density in heavy media and can be used to enrich coal, ores and building materials.

The aim of the invention is to increase the reliability of the separator with a simultaneous increase in its production;

FIG. 1 shows a solid medium separator, general view; figure 2 - dazrez aa in FIG. one.

i Separator m contains Yorpus 1, on which a fevatorny wheel 2 is installed, a drive 3 of an elematory wheel is a paddle mechanism, Iizm 4.

: The elevator wheel with 2 spokes 5, located two rows at each end of the wheel, rests on the horizontal shaft 6.

(Between the spokes of the elevator wheel 2, freely resting with the help of cb elements 7 on the shaft 6, the folded sheets 8 forming the separation bath 9.

The separator works as follows.

: The initial product enters the priming part of the casing 1 of the separator and BJMecTe with a heavy medium is directed B; the separation bath, the passage of the first zone of action of the rotating spokes of the wheel, which loosen and mix the heat of the original product with the yellow. by the medium. In the separation bath, the starting product is divided into sinking, and floating up fractions. The drowned fraction is lowered into the buckets of the elevator wheel 2 and, during its rotation, is unloaded from the separator. The raised fraction during the passage of the second zone of action of the rotating spokes of the wheel is loosened and advanced to the discharge threshold, where it is unloaded from the separator by a mechanism. Repeated loosening contributes to more effective separation separation of fracdiums, allows to increase the speed of movement of the initial product in the separator body and, consequently, increase the separator productivity, since it is determined by the amount of the initial material that has passed per unit of time through the cross section of the separator.

emerged fraction buckets Elevator wheel.

The elevator wheel, when rotated by the buckets, partially moves the heavy medium to the part of the hull where the buckets emerge from the heavy medium and additional flows are created in the hull that do not coincide in direction with the technological flow. The free suspension of the sheets by means of connecting elements forming the separation bath allows them to simultaneously deflect a certain angle around the wheel axis under the action of these flows to balance the pressures of the flows on one side of the sheets and the component mass of these sheets opposing this deviation, and to exclude voltage from the action of these flows, the deviation of the separation bath under the action of the flow of a heavy medium during the operation of the separators is maximum полож relative to the position of the bath in the idle separation Ore. In order to reduce the influence of heavy medium flows on the position of the sheets, they can be made non-slotted, and from a grid with holes 2-3 mm smaller than the minimum grain size of the enriched material.

Installing the spokes of the Elevator wheel in 2 p. Yes on the wheel disks increases the stability of the wheel, allows free access to the sunken product in the buckets. The free suspension of the sheets forming the separation bath removes the effect of dynamic loads on the flows of the heavy environment on the sheets and body parts. All this allows to increase the reliability of the separator.

The floated product, along with a portion of the heavy medium, is discharged from the separator to the next chain link of the coal preparation plant, ore, or building materials through a discharge threshold.

The sunken product is lowered into the buckets of the elevator wheel. As the wheel rotates, the heavy medium leaves the buckets through the slots and returns to the separation tank, and the sunken product is unloaded from the buckets after passing or the maximum lift height in the wheel. The frequency of rotation of the wheel in the separator is similar to the frequency of rotation of the wheel of separators of known structures (within 1-2 minutes).
