3. A device according to claims 1, 2, characterized in that the ends of the teeth of the comb are bent and arranged parallel to the bottom of the chute.

The invention relates to devices for treating wet and dry materials and can be used in the construction, mining and other industries. According to the main auth. No. 636026, a device for processing wet bulk materials is known, comprising a chute, a rotary crusher and a classifier installed in the bottom of the supply chute and communicated with the crusher cavity through a branch pipe for a product, one wall of which is a partition wall reinforced across the width of the classifier and located to the entire length of the crusher to a depth of the horizontal axis of the rotor. The feedstock entering the feed chute is fed to a classifier, where it is classified into a non-graded product with a large class and undersize product of a small class. The oversize product enters the grinder into the crusher, where it is finely crushed and extracted from it. The undersize product enters through the nozzle, into the crusher compartment, separated from the rotor by a partition, from where it is not subjected to crushing, and l is removed. A disadvantage of the known device for treating wet bulk materials is the comparatively low efficiency of the classification process, since large particles of a product moving by classifier prevent the passage of smaller particles through the holes of the classifier. The purpose of the invention is to increase the efficiency of the classification process. This goal is achieved by the fact that in the device for processing wet granular materials in the bottom of the feed chute, a rattling device in the form of a gear comb mounted at an angle of 5-35 to the classifier is mounted above the classifier. The distance between the teeth of the comb can be increased to its end. The ends of the teeth of the comb are bent and arranged parallel to the bottom of the gutter. FIG. 1 shows a device for treating wet bulk materials; in fig. 2 is a view A of FIG. 1. The device comprises a crusher 1 with a rotor 2 and a feeding chute 3 with a classifier 4 installed in its bottom, at the beginning of which a screen is fixed, made in the form of a comb 5 located at an angle to the classifier 4 about 5 - 35-. The bottom of the gutter3 is set at an angle to the vertical B of 15-40 °. The comb 5 is designed in such a way that the distance between the teeth increases towards its end, with the ends of the teeth 6 of the comb 5 arranged parallel to the bottom of the groove 3. The classifier 4 communicates with the cavity of the crusher 1 by means of a pipe 7 for the sub-base product. One wall of the nozzle 7 is formed by a partition 8, which is attached in the upper part to the classifier 4 over the entire width and located along the entire length of the crusher 1 to a depth of the horizontal axis of the rotor 2. The device operates as follows. The starting product arriving along the piercing chute 3 enters the comb 5, and de predivided into coarse and fine classes. Then the small class a classifier 4 is not divided. Cheap and Excessive products. The sedentary product along with the large lass along chute 3 enters the drifter 1, where it is finely ground and extracted from it. The product understeppels through pipe 7 into the compartment of the crusher 1, separated from the rotor by a partition 8, from where it is removed without being crushed. During the rotation, the rotor 2 of the crusher 1 creates an air flow, which is looking for a classifier 4 from Havavniiiunx) of its material.

Thus, the installation in the bottom of the gutter, at the beginning of the classifier, the roar in the form of a comb at an angle to the classification of the torus 5-35 contributes to the efficiency of the classification process for. a pre-release expense from the product of its major classes.

Installing the comb 5 at an angle to the classifier 4 less than 5 ° is impractical because it leads to an irregularly overestimated length of the cantilever comb 5. It is also impractical to mount the comb 5 at an angle to the classifier large 35 as this increases the absolute angle of inclination (I. + (B) the plane of the comb 5, the free movement of the processed product along it.

The filling of the comb 5, with the distance between its teeth, which are increased by the end of the comb, includes the possibility of jamming of particles of material between the teeth.

Execution of the ends of the teeth 6 of the comb 5 parallel to the bottom of the idapoba 3 reduces the depth of the complaint 3 and reduces the blows of large pieces of material on the surface of the bottom of the chute 3 and the classifier 4.

Therefore, the installation of a comb contributes to the increase in the efficiency of the classification process by combining a comb before the classifier of large classes of mat & rial.
