The fine 5 to 15 micron airborne lead oxide dust flying within the hood around the vibrator is sucked in to the dust collector by air currents developed by 0.5 to 0.7 m/s air rushing in to the hood through the front door. The dust laden air then passes through the filter cartridges where dust particles are collected on the filter element surface and 99.99% clean air is exhausted out to atmosphere.
Due to dust collected on filter surface, the differential pressure across element starts to increase and during operation it remains steady between 100 to 150 mm WC indicating healthy operation of the unit. |
