ROTARY-CENTRIFUGAL DISPERSANT Russian patent published in 2022 - IPC B02C18/00 

FIELD: waste recycling.

SUBSTANCE: invention relates to the field of grinding of solid waste, namely to devices for grinding with knives or other cutting or tearing bodies. A rotary-centrifugal dispersant consists of cylindrical case 1, in which loading chamber 3, screw nozzle 8, and a removable working element are sequentially located on the same axis and rigidly connected to each other. The case with devices placed on its axis is located in a horizontal plane, and the working element is made in the form of a rotor with cutting grooves located at an angle of 5-10° to a rotor axis. Screw nozzle 8 is made in the form of a hollow cylinder with nibs located on an outer surface of the nozzle at an angle of 40-45° to the rotor axis, while a cutting part of the rotor is embraced with a removable ring placed inside the case, an inner surface of which has grooves of a triangular cross-section. Moreover, the dispersant is equipped with a mixer, which is made in the form of a fan impeller rigidly fixed on a shaft and closed with a steel ring with a central hole from a side of the cutting device in such a way that a central part of the impeller is opened for passage of material. At the same time, an acceleration ring is located behind the impeller for increase in the intensity of impact of turbulent movement of air mass, and a funnel is located above the impeller for supply of dry fine-dispersed additives.

EFFECT: dispersant provides reduction in electricity consumption, increase in the quality of material grinding.
