Abstract

This invention relates to the beneficiation of minerals. The goal is to increase the enrichment efficiency by reducing the effects of large-scale turbulence and increasing the wear resistance of the drive. In the fixed case (K) 1 of the Jigging MauiHHbi is located the duct 2. In the duct 2 sedimentary sieves 3 and 4 are rigidly fixed. Along K 1, tightly hollow drop-shaped floats 15 are fixed below sieve 3. The latter are adjacent to sieve 3 by a narrowing part. During the operation of the depositor, the material to be divided is fed to sieves 3 and 4. Sieve 3 and 4, together with duct 2, oscillate in a vertical plane. The hearth mass is stratified into concentrate and rock, which are separated from the process separately. Due to the presence of floats 15, the maximum scale of turbulent eddies is reduced. The flow of fluid, the passage between the frontal parts of the floats 15, falls into the zone between them. During the upward stroke, the latter works as a diffuser, and during the downward course - as a confuser. This improves the conditions for weighing and separating the material and reduces its mixing. 2 Il. S

Fine coal

FIG. one

The invention relates to the enrichment of minerals, namely, the separation of material according to density, and can be used in the mining, ore processing and other fields of industry.

The purpose of the invention is to increase the enrichment efficiency by reducing the effect of large-scale turbulence and increasing the wear resistance of the drive.

FIG. 1 shows the proposed jigging machine, general view; in fig. 2 shows section A-A in FIG. one.

The machine consists of a fixed corner 1, in which a box 2 is installed with a horizontal 3 rigidly fixed in it and inclined 4 jigging screens. The housing is pyramidal in shape and provided with holes 5 for removing fine coal. In the upper part of the movable duct, hinges 6 are installed, which through flat springs 7 are connected to hinges 8 fixed on the machine body on the frames 9. The duct performs an oscillatory motion from the actuator 10 mounted on frame 11. Together with the duct and sieves, the oscillatory motion unloader 12 for removing large rock. The machine is equipped with an elevator wheel with sections 13 and 14 for rock and concentrate. Along the box under the sieve sealed hollow drop-shaped floats 15 are fixed, narrower: the first part adjoining the sieve.

Otsadochna machine works as follows.

The horn mass is fed into the chute, and then falls on a sieve 3, which oscillates in place with duct 2, sieve 4 and unloader 12 located in housing 1.

When the screen passes downward, an upward flow of liquid arises relative to it. Due to the presence of several parallel floats 15 of a streamlined shape, the maximum scale of turbulent eddies is reduced. After passing the frontal part of the floats 15 thread

enters the zone. between them, having the form of a diffuser. In this zone, additional flow turbulization occurs with the occurrence of relatively small-scale eddies. This contributes to the improvement of material and material separation conditions and reduces its movement.

As it goes upwards, the stream relative to the sieve changes its direction and moves downwards. In this case, the space between the floats 15 in relation to the flow is an infuser, which ensures the maintenance of fine-scale turbulence.

Under the action of oscillations of the sieve 3 from the actuator 10 through the springs 7 and the hinges 6 and 8, fixed on the frames 9, the mountain mass is stratified into concentrate and rock. The breed is removed by the unloader 12 and falls into section 13 of the elevator wheel. The concentrate is fed to a sieve 4, the upper part of which serves simultaneously as a gate, and then to section 14 of the elevator wheel for further transportation and dewatering.

The rotational speed of the elevators provides the necessary productivity both in concentration and in rock. Small coal, the size of which is smaller than the holes in the sieve, enters the lower part of the body and through the opening 5 and the discharge device is fed for further processing.
