(57) The device for pre-heating cement raw meal for the cement clinker production comprises at least one heat exchanger line for charging cement raw meal in countercurrent flow to the hot gases drawn through the heat exchanger line and a supporting structure (19) for the at least one heat exchanger line, wherein the heat exchanger line comprises a plurality of heat exchangers (8, 9, 10) which are interconnected and through which flow can pass consecutively. The supporting structure (19) comprises stands (20) which jointly form a triangular outline (21) and serve to transfer load into at least one foundation.
