FIELD: mixing equipment.

SUBSTANCE: invention relates to the field of mixing equipment. The unit for mixing bulk materials contains a housing 1, loading 2 and unloading 3 devices, a shaft 4 located in the housing with a rotary motion drive 5 and a bump 13. A cylindrical nozzle 6 is mounted on the shaft, which has an annular chamber connected to the loading device of one of the components, and a coaxially located internal cylindrical chamber connected to the loading device of another component. Each of the chambers is equipped with spray devices arranged in horizontal rows. Spray devices are rectangular blades attached to the outer side surface of the cylindrical nozzle 6, to the end surfaces of which, the upper and lower, parallel plates are attached. The bump 13 of the mixing unit is equipped with a vertical movement device 14 and is a set of conical surfaces, the taper angles of which increase from the lower conical surface to the upper one.

EFFECT: provides a high quality of mixing, eliminates the sticking of the material on the internal surfaces of the spray devices, and also makes it possible to control the mixing modes.
