Description

 one

The invention relates to the mineral processing of minerals and can be used in the beneficiation plants and plants for the enrichment of small classes of coal, shale and other minerals.

The aim of the invention is to reduce the loss of the useful component with waste, to increase the yield of concentrate due to the intensification of the weighing of light particles in the upper from loading compartment and to improve the structure of the separation flow.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device contains a closed inclined channel consisting of two sections: upper I and lower 2, funnel 3 for feeding enriched material with perforated membrane 4, movable plates with vertical wedge-shaped partitions 5 located on the side walls of the upper compartment, and a vertical fixed wall with partitions 6 and movable plate with transverse partitions in the lower compartment 7.

The device works as follows.

The enriched MaTepjiaji is fed into the hopper 3. Here is the same 220692

Under the perforated membrane 4, additional water is supplied, which, passage: through the apertures of the membrane, i loosens the material. Pre

5 loosened material along with additional water enters the working channel of the device. By entering the zone of action of the main pressure flow of the separation medium, the material is divided into two unequal parts. Most of the material is dropped into the upper compartment 1 and the four vertical vortex systems are separated in density. Light grains

15 weighted by vertical vortices, carried through the upper cut of the channel, intermediate in density and heavy grains settle to the bottom of the channel and slide into the lower compartment

20 2 channels, where a certain amount of the original material has already arrived from the hopper The material that has entered the bottom compartment forms a moving down user, which is scrubbed by the effect of horizontal vortices. The light fractions allocated to the upper part of the bed are carried upwards in an upward flow to the upper canal branch. Then to unloading. The heavy fractions, purified from lighter components, are removed through the lower opening of the canal.
