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. An automatic control processor links the various components, and provides for sequential operation. The material is conveyed batch-wise from the chamber into the hopper, and is not dispensed into the line until the chamber access has been sealed, thus preventing backflow into the chamber.
