FIELD: process engineering.
SUBSTANCE: invention relates to mixing of loose materials and may be used in various industries. Proposed mixer comprises oscillation source and cylindrical vibration-mixing container provided with nozzle with vibro active surface arranged on its bottom and aligned with its axis of symmetry. Said surface is made up of axially symmetric polynomial surfaces constricted by two parallel planes. Acoustic concentrator is arranged between oscillation source and vibro mixing container. Round nozzle with vibration activity surface directed outward features micro relief of Fresnel lens.
EFFECT: reduced power consumption.
