ABSTRACT:
A conveyor for moving hot material at temperatures on this order of 1000° F. or higher along a trough receiving the material has one or more cooling liquid flow vessels extending over but spaced from the outer surface of a trough inner wall to indirectly cause cooling of the inner wall. A heat transfer connection conductively interconnect the vessel and the inner trough wall such as interposed thin webs or plates, or alternatively a mass of conductive beads interposed to controllably transfer heat into the cooling liquid flow vessel. A series of wear plates are clamped to a pushing side of a helical tube of an auger type conveyor, which tube can also receive a flow of cooling liquid. The arrangement of a mass of conductive beads is usable in other applications to provide a non rigid mechanical support of a controlled thermal conductivity.
