Abstract
In a method for the preheating of cement raw meal for the production of cement-clinker, in which the cement raw meal is conveyed towards the feed side of a cement clinker kiln () in at least one heat exchanger-line in counter flow to hot gases, the hot gases are drawn off via at least a first heat exchanger () connected with the feed end of the cement clinker kiln () and via heat exchanger-lines () following this first heat exchanger () and being parallel to each other. The device for carrying out said method is characterized in that heat exchanger-lines () arranged in parallel to each other are connected to at least a first heat exchanger () joined to the feed end of the cement clinker kiln.
