The invention relates to devices for the separation by size and can be used in the building materials industry, the mining, metallurgical and chemical industries.

The purpose of the invention is to increase productivity by allowing the material to be separated when it is transported on the tape in several layers.

FIG. 1 shows a diagram of the device, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device consists of an endless transport belt 1, tensioned on reels 2 and 3, one of which communicates rotation to the belt. Above the working branch of the tape on the spring-loaded plate 4 with a vibrator 5 are installed V-shaped combs 6, made of plates 7, which are set tops towards the material flow on the longitudinal axis of the belt 1. The plates 7 are reinforced for rigidity by the strips 8 and installed with a shift one relative to the other in the combs at a distance equal to the width of the plate. Between themselves, the plates 7 are installed in increments, forming gauge clicks between them, decreasing in each subsequent comb as the material travels. Plate 4 rests on elastic supports 9. On the drum 2 side, above the belt, there is a loading device (funnel) 10. Combs form separating devices installed above belt 1. successively along its length at an angle to its longitudinal axis. The plates of the dies are perpendicular to the surface of the belt 1 and parallel to its longitudinal axis.

1 children are installed with the possibility of oscillations in a direction transverse relative to the longitudinal axis of the transport tape parallel to the surface of this tape.

The diverting chutes 11, 12 and 13 and the receiver 14 serve to receive material of various sizes.

The device works as follows.

 The cherial, which is to be divided into fractions, through the funnel 10 enters the endless belt 1. When the belt 1 is moving, the material lying motionless on it reaches the first vibrating under the action

the vibrator 5 of the comb 6, the plates of which, acting on the particles of the flow, cause them to move. The material becomes mobile and is actively dispersed throughout the area of the dies 6.

The coarse fraction, not passing through the comb 6 of the first row, descends into the chute 11 along its generatrix, while the smaller fraction moves to the next row of dies 6.

When passing through the first comb, the material is formed by the strips 8 into the stream closer to the center line of the tape 1. When the material reaches the second comb 6 due to the reduction of the schag of its plates 7, the material is divided by size, the fraction not passing through the comb 6 is diverted to the estrus 12, the chalk passes and is formed by the strips 8 into the stream and reaches the next comb b, etc. Depending on the number of installed dies 6 and the pitch of the plates 7, fractions of a given particle size distribution are obtained.
