FIELD: technique designed for creation of mechanical vibrations and used for intensification of various processes.
SUBSTANCE: pneumatic vibrator has ring fixed on end of waveguide. Annular race provided on internal surface of ring is adapted for rolling of steel ball thereon. Pneumatic vibrator has air feeding nozzles. Diameter of steel ball may be changed without changing total outer diameter filled with elastic enclosure.
EFFECT: wider range of frequency and amplitude of excited vibrations.
