The present invention deals with a chute for a kiln intake housing of a rotary tubular kiln or the like, the chute having a lining composed of a refractory material and a double-walled, inwardly facing collar disposed at the lower end thereof, the collar functioning to support the lower end of the refractory lining within its metal jacket and the collar being equipped with a special coolant circulating device. The inner end of the collar is composed of support segments which are connected to each other and to a holding means, the interior space of the collar being subdivided as required in order to provide for an induced circulation of a coolant.

Intake assembly for rotary drums

A cyclone heat exchanger particularly adapted for direct heat exchange between a granular product and hot exhaust gases from a kiln used in the production of cement, the heat exchanger comprising a housing, a gas feed pipe introducing hot gases tangentially of the housing, a cover extending across the top of the housing, a discharge at the base of the housing for discharging product therefrom. The improvement consists of an immersion pipe extending through the cover and into the housing, the immersion pipe consisting of a plurality of segments extending in the longitudinal direction of the immersion pipe. Holding devices are provided for releasably holding segments in the cover.
