CONTINUOUS PREPARATION OF MULTICOMPONENT MIXES OF LOOSE MATERIALS Russian patent published in 2015 - IPC B01F3/18 

FIELD: process engineering.

SUBSTANCE: proposed method comprises continuous proportioning of components, their loading into mixer at distance from discharging proportional to bulk densities and/or particle sizes, mixing and discharging of finished mix. Loading of components is performed continuously over mixer length, up to drum discharge edge. Entire period of loading key components is divided into three equal intervals. Loading intensity varies depending upon concentration of said key component after loading period of every component is divided in at least three unequal portions. Proposed device comprises continuous mixer, dispensers of components, loaders of components and finished mix discharge assemblies. Proposed device comprises n-1 perforated pipes arranged inside the mixer in its axis and provided with drives. Perforated shells are fitted at the tube to turn thereon. In initial position, all shell holes are aligned with those in tube. Every shell is divided into, at least, three equal parts with independent turnabout tube. Note here that said every part incorporates drive for its specified turn about the tube.

EFFECT: higher quality of mixing.
