Abstract: An apparatus for dispensing granular material, such as flux powder to a mold for continuous casting of metal, has an intermediate chamber, a dispensing hopper, and a conduit communicating the interior of the chamber to the interior of the hopper. The conduit has a rotatable auger running through its length, the auger reaching from within the interior space of the chamber into the interior hopper for transferring material from the chamber into the hopper. A dispensing line communicates with a bottom of the hopper at a transfer point for receiving material from the hopper and dispensing the material toward a dispensing end of the line. Pressurized air is supplied to the line, upstream of the transfer point, and a sealing cap is provided for actuating into sealing engagement with a hopper end of the conduit. A second inlet for pressurized air is provided such that air may be supplied directly into the hopper above the fill line.
