Description

12

The invention relates to the sorting of bulk particulate materials and can be used to classify materials from the mining, chemical and other industries.

The purpose of the invention is to improve the quality of sorting the material by first separating it before feeding the blower with directional air flow.

FIG. 1 shows a conventional circuit diagram of the device; in fig. 2 - Metatella construction.

The device consists of a loading device 1, a rotary thrower 2, enclosed in a housing 3, having two continuous disks 4 mounted on a rotation shaft 5, i between which longitudinal shock plates 6 are fixed between them. In the form of an e-7, one longitudinal end of which is made with a bend 8 towards the scoop 2, the casing 3 of the scoop 2 is connected with a casing 9 in which there are receptacles 11 having concave transverse walls 10 in the form of partitions enrichment

and a receiver 12 for collecting dust particles.

The device works as follows.

From the loading device 1, the initial product is fed by a layer to the thrower 2 enclosed in the housing 3. The air flow arising during rotational movement of the impact plates 6, controlled by the position of the bend screen 7, blows the dust particles into the receiver 12 and distributes the remaining particles over the rotation surfaces of the shock plates 6. As a result, the latter come into contact with the grains of the enriched material at various points of rotation oKp iiOKHOcTH, where the angle of inclination of the working plane is p-different. Therefore, the initial angle of departure of grains is the greater and the more years they are, the farther they are. Increase the flight range of large grains contributes to their lighter sail. Moving inside the casing 9 along different trajectories of the grain of the enriched product, after hitting the walls of the receivers, the concave walls 10 of the partitions enter the receivers 11, from where they are periodically discharged.
