Abstract

The invention relates to a rotary drum with relatively large dimensions, the shell of which is supported by means of riding rings each on a pair of supporting rollers of a supporting roller stand. For this purpose the rotary drum shell merely bears two riding rings which are attached so as to be fixed against rotation and which are supported on two supporting roller stands of which at least one simultaneously forms the rotary drive arrangement for the rotary drum in the form of a friction drive. This produces a combination of features by means of which the mounting of the rotary drum is statically determinate and can be driven reliably in an extremely simple manner.
