VIBRATION MIXER Russian patent published in 2013 - IPC B28C5/16 B01F11/00 

FIELD: process engineering.

SUBSTANCE: invention relates to concrete mixers and may be used in other fields of construction. Said mixer comprises mixing chamber with material loading and discharge openings, vaned rotor and rotary drive. Top and bottom vibrators are rigidly secured at the center of mixing chamber top and bottom parts: bottom and top vibrators to excite two equal-amplitude different-frequency vibration fields by top and bottom crank gears. Vibrator case is composed of metallic corrugated shell. Said shell is composed of thin-wall corrugated solid of revolution that forms truncated ellipse in vertical plane section over crimp peaks points. It allows generating opposite direction oscillations. Disk with guide post is secured inside shell, at the center of horizontal plane. Top and bottom vibrator disks have cylindrical ledges with rods rigidly secured to their inner parts centers and pushers attached to outer parts centers, opposite ends of said pushers being rigidly secured to inner parts forming smallest crimps of corrugated shells. Four ledges are secured in symmetry to barrels outer cylindrical surfaces. Spring is arranged between cases of top and bottom vibrators, at the center to excite additional vibrations of mixed components from cases of said vibrators.

EFFECT: ruled out "dead" zones.
