Anand,

This is a simple matter. If you know the venting airflow from each airslide, size the individual ducts for 20 m/s. Enlarge the ducting at each junction to maintain 20 m/s. Fit a slide damper at each branch to allow tuning/balancing.

Hi

Inter venting is common.

I would not worry about 20m/sec...make your ducts steeply sloping and generours.

Do not worry about slide gates.

I am assuming that each airslide unit has it own aeration system ie fan or blower.

I have done this with success in transfer plus also change of directions >> this is where the conveyed material can be very turbulent in the divertor pot and this turbulence actually blocks off the vent air inside the airslide.

You may need to have expansion compensators in the ducts if there are same in your material side hardware.

If you have a long network - the de dusting volume will become higher - so you will need to look at your de dusting hood / take off design > do not wnat to draw off excessive dust from the airslide...

Be wary of condesation, moisture ingress if your system is located outdoors - may need lagging

Cheers

Pls refer to the Industrial Ventilation handbook

I would look at hood velocity of around 1.5 to 2m/sec max.

You do not want to pick up large particles - so do not place hood next to highly agitated flows

Thanks ■
