Abstract: FIELD: machine building. 
     SUBSTANCE: vibration mixer comprises a mixing chamber, a rotor with blades. In the top and bottom parts of the mixing chamber, two vibrators are set in the centre and rigidly fixed: the lower and upper vibrators are made in casings and generate vibrations by lower, central and upper crank mechanisms. The vibrators' casings are made as metal corrugated shells being corrugated thin-walled bodies of rotation which in the vertical plane section provide for complex truncated geometric figures by corrugation peaks points, the figures are formed by central intersection of four circles with the centres being the vertices of a square and with the radiuses being equal to the diagonal of the said square, the shells are able of generating three vibration fields identical in amplitude and different in frequency, two of the fields in the aggregate and one field separately correspond by shape to the corrugated contour of the said bodies of rotation, with differently directed oscillations. A disk is rigidly fixed inside the shell of the lower vibrator in the centre in the horizontal plane, it is fitted with a cylindrical protrusion able of being inserted and fastened along the inner diameter of a spring installed so that it can be freely compressed/released in a cup. A connecting rod driven by the central crank mechanism is rigidly attached to the centre of the upper inner part of the cup. A pusher is attached to the centre of the cup's upper outer part, the pusher is rigidly coupled by the other end with the inner upper part of the lower vibrator casing shell and can generate vibrations from the upper part of the lower vibrator casing via the connecting rod by the central crank mechanism. The lower vibrator disk provides for the possibility of generating vibrations of the central part of the lower vibrator casing with the help of four pushers which by their upper part are symmetrically attached to the lower part of the disk and by the lower part are coupled in a movable pivot unit of the connecting rod of the lower crank mechanism. A disk with a guide post is rigidly fixed inside the shell of the upper vibrator in the centre in the horizontal plane, the guide post is to provide for stable directed translatory motion of a stem from a sliding pair formed by the guide post of the upper mixing chamber part, the guide post of the blade rotation drive and upper vibrator stem of the upper crank mechanism, it is fitted with a cylindrical protrusion able of being inserted and fastened along the inner diameter of a spring installed so that it can be freely compressed/released in a cup. The stem is rigidly attached to the centre of the cup's inner part, and a pusher is attached to the centre of the cup's outer part, the pusher is rigidly coupled by the other end with the inner part forming the smallest corrugation from those of the upper vibrator shell. Four protrusions are symmetrically set on the outer cylindrical part of the cup. A spring vibration generator made as a spring set is installed in the centre between the casings of the lower and the upper vibrators, the spring set consists of at least two springs of different diameter which are fixed along the diameters of recesses formed on the outer surface of the metal corrugated shells by the set of the smallest corrugations from those of the lower and upper vibrators. 
     EFFECT: qualitative intensification of component mixing process on the whole.
