ABSTRACT:
An apparatus for partially drying and feeding material from an external source into a drying mill is disclosed. A conduit comprising first and second wall members and having an annular cross-section substantially throughout its acial length is connected to one end of a receiving chamber. Means are provided for guiding the material to be dried from an external source into a receiving chamber and for depositing the material in an area within the receiving chamber which is substantially coaxial with the conduit. Hot gases are introduced into the receiving chamber and propelled into and along the annular conduit with a generally circumferentially cyclonic flow. As the gas proceeds through the conduit, it carries with it the material deposited in the receiving chamber and feeds it into a drying mill.
