Abstract: FIELD: machine engineering. 
     SUBSTANCE: vibration mixer comprises a mixing chamber with the ports for loading and unloading materials respectively, a rotor with blades and rotary drive. In the top and bottom parts of the mixing chamber, lower and upper vibrators are set in the center and rigidly fixed, they are made in corrugated casings and generate vibrations by the lower, central and upper crank mechanisms. Inside the lower vibrator body there is a disc with a cylindrical protrusion rigidly fixed in the center in the horizontal plane configured to enable inserting and fixing spring along the inner diameter installed with a function of free compression/extension in cup, which inner parts center is rigidly fixed to the connection rod with the center crank mechanism drive, and which upper outer part center is rigidly fixed to the pusher rigidly connected to the inner upper part of the body with the other end and configured with the function of oscillation excitation from the upper part of the lower vibrator body through the connection rod by center crank mechanism. The lower vibrator disc is configured for generating vibrations from central part of the lower vibrator casing with the help of four pushers which are symmetrically attached by their upper part to the lower part of the disc and are coupled by the lower part in a movable pivot unit of the connecting rod of the lower crank mechanism. Disc with a guide post is rigidly fixed inside the upper vibrator body in the center in the horizontal plane which function is to create stable directed translational motions of the rod from the prismatic pair formed by the guide post of the upper part of the mixing chamber, guide post of the blades rotation drive and the rod of the upper vibrator, the upper crank mechanism and a cylindrical protrusion configured to enable inserting and fixing spring along the inner diameter installed with a function of free compression/extension in cup which inner part center is rigidly fixed to the rod, and outer part center is rigidly fixed to the pusher rigidly connected with the other end to inner part which forms the smallest one of the corrugations, upper vibrator body, and configured with the function of oscillation excitation from the smallest of upper vibrator body corrugation. Four protrusions are symmetrically fixed along the outer cylindrical parts of the cups. Bodies of the vibrators are made in the form of metal corrugated shells representing corrugated thin-walled bodies of rotation which form truncated regular octagons in section of vertical plane by points of corrugations apexes and made with the possibility of creation of three vibration fields similar in amplitude and different in frequency, two of which correspond together and the third corresponds individually to the shape of corrugated contour of said bodies of rotation with differently directed oscillations. A spring vibration generator made as a spring set is installed in the center 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 of the lower and upper vibrators. 
     EFFECT: expanded range of operating means and provided intensification of the mixing process.
