LOOSE MATERIALS GRAVITY MIXER Russian patent published in 2018 - IPC B01F9/02 B28C5/04 B28C5/20 

FIELD: machine building.

SUBSTANCE: invention relates to the field of construction machine building, namely to the loose mixtures preparation devices. Loose materials gravity mixer contains the housing held by a mobile cross-beam fixed on supports, by the axis connected to the slow-speed reducer paired with the engine, housing is made in the form of a dumbbell of two conical chambers connected by a pipe, and on each chamber and the pipe border a slide gate is built-in, actuated by the electromechanical mechanism. Loose materials mixing is carried out by the materials flowing out from one chamber (upper) into another (lower) in a free flow, when under the action of gravity the particles of materials are stratified in the flow, moving in the arbitrary order, practically free of friction forces, actively mixing into the multicomponent mixture, contributing to their quality mixing. For mixing with a mixing ratio close to 100 %, it is sufficient to make several rotations of the chambers. Mixer design activates the material particles gravity forces, which tend to lower the materials grains down and promoting their stratification, and the dynamically trapped descent of materials from one chamber to another, promoted the bulk materials complete mixing.

EFFECT: invention provides improvement in mixing quality.
