High-frequency vibration structure: It mainly composes of sieve box, vibration device, suspension (or support) device and electric motor.The motor passes through the triangle belt to drive the spindle rotation of the vibrator. Due to the centrifugal force of the unbalanced heavy objects on the vibrator, the sieve box vibrates. It changes the eccentric weight of the vibration device to obtain different amplitudes. Product characteristics: 1. No rotating parts, and no lubricating oil is required; 2. Simple structure, convenient maintenance, durability and low failure rate; 3. The vibrator uses the resonance principle, the double mass critical resonance state work, the required driving power is small, no large starting current at the starting time, the noise is low; 4. After the vibrator is started, the amplitude can instantly reach the operating stability value.When parking, its amplitude is instantly disappear, flat and allowing direct start and stop at rated voltage, current and amplitude. 5. The shock or amplitude of the sieve body can be adjusted; 6. With the vibration of the sieve body, a relative tremor also produces between the sieve strips, and the sieve gap is not easy to block.
