Abstract: A device for driving a rotary sieve device, which device comprises at least one drive set that is connected through a transmission with one or more rotatable sieve surfaces which are placed in a housing.The novelty is the pneumatic tire mounted on a wheel that is fastened to a bushing mounted on the outgoing shaft of the drive set. The running surface of the pneumatic tire contacts a drive surface on the outside of the housing, which is connected by means of a horizontal leg to a vertical ring fastened below the sieve surface.This arrangement provides for the slippage and/or elastic deformation of the pneumatic tire in case of shocks or impact loads on the sieve surface by sudden amounts of material to be sieved through the sieve surfaces.
