PROCESS MODULE FOR PREPARATION OF HETEROGENEOUS COMPOSITE MIXTURES Russian patent published in 2020 - IPC B01F7/08 

FIELD: construction.

SUBSTANCE: invention can be used for making construction and architectural and construction articles for preparation of composite mixtures with heterogeneous components in production of mechanically activated composite mixtures with anisotropic fibrous fillers used in 3D-technologies. Process module consists of in-series installed vertical and horizontal mixers with blades. Blades of vertical mixer are made double-helical in form of helicoidal surfaces of unidirectional approach, shifted relative to each other by angle ϕ₁=90°, with louvers fixed on radial rods with turning angle α_v=10–45°. Horizontal mixer is divided by conical inserts into three chambers. First chamber accommodates single-threaded screw blade with solid working surface. In the second chamber of the horizontal mixer, in parallel and in opposite directions double-helical helicoid blades with rod working surface and displaced relative to each other by an angle ϕ₂=90°. In the third chamber there are double-helical blades unidirectional towards material unloading with continuous belt working surface of height h=(0.5–0.8)r_kor and displaced relative to each other by an angle ϕ₃=45°. Required volumes of liquid additives and liquids are supplied for semi-dry and wet methods of preparation of mixture through feed pipes for supply of additives and liquid to the third chamber of horizontal mixer.

EFFECT: expansion of technological capabilities of the module due to possibility of mixing components of different dispersion and granulometry with fibrous fillers at dry, semi-dry or wet methods of preparation of mixtures.
