There are two superimposed pressure vessels, the upper of which has a closable material inlet connected to a source of fine material and has a lower end in the form of a cone with a bottom outlet. The lower pressure vessel has a material inlet which is connected through a valve to the bottom outlet of said cone, and has a pneumatic feed conduit connected to its lower portion as a material outlet. A conduit is connected to both vessels for equalizing the pressure therein after the inlet of the upper vessel has been closed and before said valve is opened. A plurality of nozzles are uniformly distributed throughout said cone and are connected to a source of gas under pressure for aerating material in said cone, each of said nozzles having an inside diameter between 0.2 and 0.6 mm.

Pneumatic pressure conveyor for fine material

This invention relates to a method and a device for the continuous feed of a controllable amount of powder material from a storage container to a consumer, using a vertical pneumatic conveyor, to which is fed conveying air, with loosening air supplied to the base area.

Method for feeding powdered material

A silo for mixing and homogenizing bulk material has an air permeable base above a mixing chamber having a volume less than that of the silo, the chamber also having an air permeable floor, and the chamber being in communication with the silo by at least one material inlet aperture and having at least one material outlet aperture.

Silo for mixing and homogenizing bulk material

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.
