The drawing shows schematically a mixer, a longitudinal section.

The mixer comprises a housing 1, inside of which is a rotor 2 and coaxially ramedelenny R him the shell 3-5 in the form of inverse truncated cones. The conical rotor is fixed on the shaft 6 installed in the bottom 7. The rotor drive is dried from the engine 8 using a wedge-mine transfer 9. A conical insert I) is fixed in the central part of the rotor to distribute the material. Shell 3-- 3 placed PA hollow concentric shafts 11 - 3, installed in bearings 14-16. Drive shafts osus. Gs1vets from the engine, I am 17 with rioMouibio V-belt transmission with 1 18kIw 18. The shells 3-5 are connected with the means of the vertical reciprocating movement 1i with the cams 21-23 and the springs 24-26. On the outer surface of the shells, concentric partitions 27--29 are fixed in the form of straight truncated cones. The cams are located on hollow shafts 11-13 and interact with the stops 30--32. For unloading the material is 11at) slaughter 33.

The mixer works as follows.

The initial components are fed to the displacement through the hollow shaft 1 1 of the lower shell 3. Fall onto the insert 10. they evenly spread over the surface of the rotating Pter rotor 2 and move to its edges. At the same time, the velocities of the components of the mixture in height from; 1о differ slightly which corresponds to the laminar mode of movement of materials. However, this does not correspond to the) Ovani intensive mixing of components. For the turbulization of the layer

components are conical shells 35, which simultaneously perform rotational and reciprocating rims. Up until the moment when cam 21 and abutment 30 come into contact between the 1 h edge of the spacing 27 and rotor 2, there is a gap sufficient for a normal passing of the material . At the time of the running of the cam on y; iop 30, the shell 3 alternates down and the bottom of the partition 27 is immersed in a layer of material, and its movement is braked. This forms a concentric material roller at the inner surface of the partitions. When the cam comes out of contact, with an emphasis, due to the action of the spring 24, the shell 3 moves to its original position, and the material begins to move again to the edges of the rotor, evenly spreading along its surface. Those particles of the material that are retained by the overlap rod during rotation of the shell are discharged as a result of the centrifugal action. 1.

Sometimes matter. out of the zone of action of the partition 27. It falls within the scope of action n (re | -orodok 28 and 29.

Depending on the type of the mixed materials and on the distance of the shells from the axis of the shaft, each sheath immerses the partitions into the layer of material according to a definite law. For example, in the area of the rotor, closer to the axis, mix; 1I do the action of the shells with a partition on them. The material is more intense and the law of their movement is more rigid (aperiodic law with a large gain factor and a short time). Upon further movement of the material along the rotor, the action of the shells on it is less intense and softer, since in this part of the rotor, I11 is intensive; 1ness of unreactivity decreases. It is also due to si, 1 internal friction in the material, depending on the distribution of its particles. in height

The proposed increase in the mix; 1 per unit, more intensively interchanging the material, reducing the specific energy consumption, as well as getting more with the homogeneity n 1 (using initial components).
