VIBRATORS

Duplex electromagnetic vibrators provide powerful vibration by energising the electromagnet of the vibrator by the pulsating current obtained through the rectifier. The amplitude of the vibration can be controlled to suit individual requirements by a controller. Duplex vibrators can be used for: vibrating bins and hoppers - to keep materials flowing freely; vibrating forms - to eliminate air pockets and voids; vibrating containers - to increase their weight contents; vibrating chutes - to ensure steady flow; and vibrating screens - to increase capacity. The choice of the proper size vibrator depends upon: purpose of vibration - to flow material or to compact or settle it; character of material - whether dry and free or moist and sticky; the weight of material to be vibrated; and the rigidity, ie, thickness of the hopper, chute or form.
