HOW IT WORKS: Air pressure activates the multi-slotted vane on two rollers (one within the other) which creates multiple vibrations on each orbit; this produces a powerful force at a high frequency.

KEY FEATURES:

  • This series of vibration solutions are the original heavy-duty vibrators specified and used by precast producers.
  • There are no bearings, seals, or O-rings.
  • 3 moving parts (vane, roller-vane, inner/outer roller) provide for simple, long-wearing vibration requiring minimal maintenance.
  • Shaft, roller, and endplates are hardened and ground to assure high performance and reduced wear.
  • Frequency ranges between 4000 and 16000 vpm depending on the type of vibrator and air pressure applied.
  • It produces a powerful output force ranging from 1000 pounds up to 5500 pounds.

COMMON VIBRATION APPLICATIONS:

  • Concrete Precast: dual roller vibrators leave larger aggregates relatively undisturbed which lessens the chance of segregation; by moving only the fines of the mix and removing entrapped air, dual roller vibrators help to produce a much higher concrete density.
  • Other Concrete Applications: concrete screeds, concrete pipes, prestressed concrete, and more…
  • Other Common Applications: refractory
