ABSTRACT:
A rotary kiln has a generally cylindrical housing centered on and extending along an axis inclined to the horizontal and having an upper upstream end and a lower downstream end and a drive that rotates the kiln about its axis. Particles to be heat-treated are fed into the housing at the upstream end and are extracted from the downstream end. A plurality of axially separate heat-exchange radiators fixed in the housing are connected axially in series and a fluent heat-exchange medium is flowed serially through the radiators from the downstream end of the housing to the upstream end of the housing.
