I am working on a project to pneumatically convey petcoke (90 µm & 0.5 t/m) for 150 ft. from a tanker to four silos (10 m each) which are placed in series. Tanker capacity is about 10 tons and we need two trips per day at different intervals. Petcoke once transfered to the silos will be continuosly consumed by the burners (4 nos.).

What is the best and economical method to fill all the silos equally during the each load transfer from the tanker?

The silos are 120 ft. from the ground level and only one trasfer pipe allowed from the tanker to the silos.

The silos are vented and connected in series to a single baghouse.

Will there be any excessive back pressure if the silos are vented in series to a single baghouse that hinders the transfer of material from the tanker?

The operation should be automated fully without engaging any man.

Suggestions and practical ideas are welcomed.

Thank you ■
