Abstract
A drum or drum segment for a drying apparatus of pourable material having built-in components arranged within the drum, which is rotatable about its central axis. The built-in components thoroughly mix and convey the pourable material from a drum entrance to a drum exit while guiding through a tempered gaseous transport fluid. Several support rings are arranged between the built-in components and the drum. The support rings are arranged to be statically supporting, but compensate tensile and compressive stresses in an elastic manner. The support rings are connected to the built-in components, a support frame and the drum, or a combination thereof A method for producing the drum or drum segments includes pre-mounting modules of built-in components and inserting the modules of built-in components into the drum or the drum segment.
