VIBRATORS

ELECTRO MAGNETIC VIBRATORS
VIBRANT Electromagnetic vibrators are used for:
  • Vibrating Bins & Hoppers for smooth flow of material.
  • Vibrating chutes to ensure steady flow of material.
  • Vibrating sieve (screen), to sieve material of different sizes at controlled rate.
  • vibrating containers to increase their net weight content.
  • compacting materials to eliminate blow holes.

The amplitude of these vibrators can be varied over a vide range by the controller supplied with the vibrator. This enables uninterrupted flow of material under varying conditions. These vibrators, vibrates at a frequency of 3000 VPM and are designed for continuous operation.

The proper selection of vibrator depends on many factors:
  • The purpose of vibrator i.e. flow the material, compact it or settle it.
  • The weight of the material to be vibrated.
  • The characteristics of the material.
  • The design of the hopper & its installation in the system.

The general selection chart for hopper is given in the following table. The size of the vibrator depends on the wall thickness of the hopper/bin. The number of vibrators to be used depends on the capacity of the hopper.

The most ideal installation of vibrator is at 1/4 or 1/3 of its slope length of hopper from the discharge. If more than one vibrators are required to be installed on one hopper they should be equally apart and should be connected in the same phase of supply.
