A screening apparatus for granules or the like material comprises a housing, wherein a frame structure is arranged which is rotatable about a main axis. The frame structure supports a screen drum which is rotatable by means of a shaft arranged eccentrically with respect to the main axis. In order to readjust the screening apparatus from screening one material and to screen another material which needs another contribution of the centrifugal force from the planetary movement of the screen drum, the eccentrically of the screen drum with respect to the main axis is variable. |
