The article is devoted to the development of special ultrasonic device with vibratory system for imposing of mechanical vibrations to the atomizing nozzle at atomizing of aluminum. The construction of ultrasonic vibratory system with the flowing cooling volume for compensation of a nozzle heating by molten metal is describes. The article presents data on practical application of ultrasonic device for the existing production process of obtaining aluminum powder. The obtained results show the effectiveness of ultrasound treatment to increase the fine fraction of aluminum powder.
