Abstract
A rotary drum having a toothed rim arranged on the drum casing and supported at several peripheral points on the drum casing by evenly distributed bridge members. Each bridge member includes two clips axially spaced from one another and welded to the drum casing and a cross plate which connects the clips and is radially spaced from the drum casing. Each cross plate is rigidly connected to one clip and slideably connected in the axial direction to the other clip so that differing degrees of thermal expansion and resulting deformation of the cross plates and further strain on the cross plates, clips and connection points can be compensated for.
