ABSTRACT:
An apparatus is disclosed in which a raw material feed delivery pipe is connected to the periphery of a vertical conduit that receives gases from a rotary kiln and conducts such gases upwardly to a location where the gases are divided between a pair of cyclone gas-solids-separator heat exchangers comprising a first stage of raw material preheating. An axially movable and rotatable sleeve is mounted over the discharge end of the pipe, and the sleeve is provided with a terminal nozzle portion curved to discharge raw material at an obtuse included angle to the axis of the delivery pipe. A method is disclosed by which the sleeve is moved along the pipe and rotated relative to the pipe, to change the nozzle discharge location and deflection angle relative to the rising gas stream, until an equal temperature drop of gases in both heat exchangers is achieved and balanced loading thereof is thereby indicated.
