Description

one

The invention relates to a device for the separation of materials by size and can be used in the beneficiation of minerals and in other areas of the national economy.

The aim of the invention is to increase productivity and efficient sorting by preventing jamming and clogging of the chalk discs. Which faction.

Fig, 1 shows a sorting device, a general view; in FIG. 2, the same thing is a look; FIG. 3 is a section A-A in FIG. 2.

The sorting device contains a horizontal shaft 1 installed with the possibility of adjusting the rotational speed, with cone disks 2 fixed on it, made of elastic material, loading tray 3 with grooves located between the disks, made of parforium | A mower and setups with the possibility of adjusting the gap relative to the Lobs and the base of the discs; receivers 4 of sorted material with cutters 5 located between the discs, squirted 6 mounted above the shaft with the discs and the boot tray and under the boot tray, supports 7, the gap between the bases of the discs and the core

BAM boot tray is made equal to the size of the perforation holes. The device works as follows.

The source material enters the perforated tray 3, where during transportation and watering some of the fine and clay particles are carried under the bottom of the feed chutes through perforations, the size of which is pa3Mejiy fines (for example 3 mm) obtained by separating on a shaft with disks 1 Here, in the process of dying, additional segregation takes place due to the fact that fine particles of the material are carried away with water from the splashed 6 installed above the feeding chutes and the shaft into the lower part of the layer of material. Reaching the end of the feed chute, part of the fine particles passes through an adjustable gap between the chute and the shaft (the gap size is also set depending on the size of the fine fraction obtained during sorting, for example 3 mm. And finally, after entering the interdisk space of the rotating shaft, the grains will be located on different pads from the axis of rotation depending on the dimensions. At the same time, due to the mechanical agitating of the material by the water jets, small particles are directed closer to the shaft axis and when a certain position is reached They are located in the interdisk space and continue to move along a circular path to the place of unloading, which is carried out by the cutters 5. The assorted material is collected in the receivers 4. The shaft with the disks rotates in the supports 7.

It should be noted that the rotational speed of the shaft is chosen such that the fine particles together with the water can be discharged into the corresponding receiver both from the side of the unloading and from the side of the feeding chutes. move against shaft rotation.

A portion of the fine material left in the thin slits of the discs is washed out with strong jets of water from the spray 6 located under the feed chutes.
