DEVICE FOR THE PNEUMATIC WITHDRAWAL OF FINE MATERIAL FROM A SILO CONTAINER

摘要

Apparatus for withdrawing fine material from a silo having a base sloped toward a discharge zone comprises a chamber within which an air feed nozzle registers with the lower end of a conveyor conduit which extends upwardly out of the silo. Fine material is admitted to the chamber via apertures and is entrained in air passing from the nozzle into the conduit.
