The working part of the Teyafei vibrator is a rod-shaped hollow cylinder with eccentric oscillator inside. The high-frequency and small-amplitude vibration is produced by high-speed rotation driven by the motor. The vibration frequency can reach 12 000-15 000 times/min. The vibration effect is good, the structure is simple and the service life is long. It is suitable for vibration beam, column, wall and other components and mass concrete.
