METHOD OF CONTINUOUS PREPARATION OF MULTICOMPONENT MIXES AND DEVICE TO THIS END Russian patent published in 2013 - IPC B01F3/18 B01F9/02 B01F15/02 

FIELD: process engineering.

SUBSTANCE: invention relates to processing of loose materials, particularly, to continuous preparation of multicomponent mixes. 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. Continuous loading is carried out in irregular way. Entire period of loading key components is divided into three equal intervals. Loading intensity varies depending upon concentration of said key component. Proposed device comprises mixer, proportioner, components loaders and finished mix unloaders. It incorporates n-1 perforated tubes with drives of rotation. 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 turn about tube. Note here that said every part incorporates drive for its specified turn about the tube.

EFFECT: higher quality of finished mix.
