HYDRAULIC DISPERSION-MIXING UNIT TO PRODUCE HIGH-ADHESION BINDING AND FINE CONCRETES Russian patent published in 2014 - IPC B28C5/14 

FIELD: process engineering.

SUBSTANCE: invention relates to the production of high-adhesion binding and fine concretes. The proposed hydraulic dispersion-mixing unit to produce high-adhesion binding and fine concretes comprises a frame and a screw auger. The screw auger blades have shaped holes that vary subject to the auger sizes: the number of holes increases from "n₁" at the auger initial part to "n_m" at the auger end part; the size of holes decreases from "k₁" at the auger initial part to "k_m" at the auger end part, all the holes being located radially around the circle on the surface of blades.

EFFECT: superfine suspension-emulsion binders with higher adhesion to a solid surface are obtained.
