Abstract: FIELD: construction. 
     SUBSTANCE: vibration mixer with a mixing chamber with material loading and unloading windows, a rotor with blades. In the lower and upper parts of the mixing chamber, the following is rigidly fixed in the middle: two upper and lower vibrators in corrugated housings with vibration excitation by the lower, middle and upper crank mechanisms, and a function to create the effect of blending vibration fields in the mixing chamber center from the bottom and top vibrator, respectively. At that, in the lower vibrator housing provided with a function of generation of two vibration fields with identical amplitude and different frequency using the upper and lower crank mechanisms, in the middle in the horizontal plane a disc is rigidly fixed with a cylindrical projection with a possibility of inserting and fixing of a spring in the inner diameter, the spring is mounted with a function of free compressing/decompressing in cup, with the middle drive crank mechanism rigidly fixed to the upper inner part center and a pusher fixed to the upper outer part center; the other end of this pusher is rigidly fixed to the upper inner part of the lower vibrator housing and provided with the function of vibration excitation from the upper part of the lower vibrator housing through the crank by the middle crank mechanism. At that, the lower vibrator disc with the function to provide uniform distribution of vibration field throughout the mixing chamber volume from the upper to the lower part of the lower vibrator housing by creating homogeneous amplitude values of displacement of each point of the outer generatrix of the corrugated housing, is arranged to excite oscillation of the central part of the lower vibrator housing by means of four pushers with upper parts symmetrically fixed to the disc bottom and lower parts connected to the movable pivot assembly the lower crank mechanism. A that, in the upper vibrator housing, a disc with a guide stand is centered horizontally and rigidly fixed, its function is to provide stable aimed rod translation from the prismatic pair formed by the guide stand of the mixing chamber top, guide stand of the blade rotation drive and upper vibrator, upper crank mechanism rod, and a cylindrical projection with a possibility of inserting and fixing of a spring in the inner diameter, the spring is mounted with a function of free compressing/decompressing in cup, with the rod rigidly fixed to the inner part center and a pusher fixed to the outer part center; the other end of this pusher is rigidly fixed to the inner part forming the smallest flute of the upper vibrator housing and provided with the function of vibration excitation from the smallest flute of the upper vibrator housing. At that, the outer cylindrical cup portion has four symmetrically mounted protrusions with the function to transmit reciprocating motion to the upper vibrator disc, capable of uniform distribution of vibration field from the smallest of the upper housing flutes to the places of upper vibrator housing attachment, by providing uniform amplitude displacement values of each point of the housing outer generatrix at the time of full compression of spring into rubber gaskets with the function of mitigation of protrusions impact with the upper vibrator disc. The vibrator housings are made in the form of corrugated metal shells, which are corrugated thin walled rotation bodies forming truncated regular pentagons in the vertical plane section by the flute vertices points, and configured to generate three vibration fields with identical amplitude and different frequency, two of them conform as a whole, and one separately to the corrugated contour of these rotation bodies, with multi-directional vibrations. At that, a spring is attached between the upper and the lower vibrator housings, at diameters of recesses formed by the smallest flutes of the corrugated metal shells of the upper and lower vibrator housings, its function is to provide an aggregate three-frequency vibration field, corresponding to the spiral shape of the spring, forming vibration fields overlapping effect dynamization and additional vibration effects on the mixed components from the upper and lower vibrator housings, respectively. 
     EFFECT: intensification of mixing of these components as a whole.
