The invention relates to devices for grinding materials, namely, disintegrants, and can be applied in the chemical, construction and other sectors of the industry.

The purpose of the invention is to reduce the size of the disintegrator, simplify the design and reduce energy consumption for processing the material.

Fig, 1 shows a disintegrator, a general view; FIG. 2 is a section A-A in FIG. 1; Fig, 3 - disintegrator, top view; Fig, 4 - the same, end view.

The disintegrator consists of a housing 1, a grinding chamber 2, which consists of a cylindrical part.3 and side walls 4, an inlet 5, two rotors, ETSi consists of carrier disks 6 with processing circles 7, a drive in the form of two electric motors 8, a number of inclined plates 9 located in the peripheral zone of the grinding chamber 2 with a gap of 10 and the cylindrical part 3, the separator 11 covers one of the electric motors 8, is between the housing 1 and the cylinder 12, is connected to the grinding chamber 2 there are directions s blades 14; In the lower part of the separator 11, a collection 15 of fine material is made; in the lower part of which is an assembly 16 for unloading fine material, for example, in the form of an auger 17 with an actuator 18, the separator 11 is connected to the return flow channel 19 with an air collector 20, enclosing the second electric motor 8, and is made between the casing-1 and cstinder 214. The air collector 20 is connected to the grinding chamber 2 on the inner side of a series of inclined plates 9 by an annular gap 22 in which the guide vanes 23 are formed. made in the form of an arcuate guide 24 and an opening 25 between the grinding chamber and the inlet 5, the separator 11 has a suction fan 26, the blades of which are located at the annular slot 13, the fan 26 is connected and rotates with the rotor bearing disk 6. In the grinding chamber, an injection fan 27 is provided, the blades of which are located at the annular gap 22,

Between the separator and the collector of fine material there is a cutter assembly in the form of inclined plates 28. To open the disintegrator, the return flow channel is made detachable along the plane 29, and the disintegrator itself has hinge assemblies 30, To ensure uniform flow of material through a number of inclined plates 9, the last processing circle is provided ventilating blades 31, to avoid the ingress of coarse material into the fine material between the fan 26 and the grinding chamber, an annular barrier 32 is made. Inclined plates 9 (blades) are made They are rotatable around the hinge 33 and form an adjustable slot 34 for separating the material. To control the amount of air performed

gate 35,

I.

Disintegrator works as follows

in the way

The crushable material flows through the inlet 5 into the disintegrator, passes through all the circles of processing and enters a row of inclined vanes 9 located around the circumference. The ground material slides over a set of inclined vanes. At the same time, the moving layer is blown by the air flow created by the rotors 6, the fans 26 and 27 and the blades 5, Through the slots 34 between the inclined blades 9, fine material flows through the annular gap 13 into the separator 11, due to the circular movement of the flow ,

0 which is created by the guide vanes 14 and the fan 26, the material is deposited on the walls of the separator, scodite on the lower part of the separator and enters the collection 15 of small material. A cutter with inclined plates contributes to the entry of the material into the collection. Air from the separator 11 enters through the return flow channel 19 into the air collector 20 and through the annular gap 22 into the grinding chamber. 4, Fine material is withdrawn from the disintegrator and collector 15 by the discharge unit 16, the coarse material slides along a series of inclined plates to the large material return unit and along the arcuate guide 24 through the opening 25, enters the inlet and, together with the fresh material, is recycled .
