(57) Method and device for the combined manufacturing of cement clinker (c) and calcined clay (d), wherein the cement clinker (c) is produced in a cement manufacturing line (10) by the steps: providing a cement raw meal (a), preheating and precalcining the cement raw meal (c) in a preheater and calciner section (11), sintering the precalcined cement raw meal in a rotary kiln (15) to provide the cement clinker (c) and cooling the cement clinker (c) with a counter current air stream in a clinker cooler (17) providing hot air, and wherein the calcined clay (d) is produced in a clay manufacturing line (20) by the steps: providing a clay raw material (b), preheating the clay raw material (b) in a heat exchange section (21), and calcining the preheated clay raw material suspended in gas in a flash calciner (23) to provide the calcined clay (d), wherein the hot air from the cooler (17) is divided into at least two streams, a first combustion air stream used in sintering the cement raw meal and a second combustion air stream used in calcining the clay raw.
