Beschreibung
Zusammenfassung:	A method for cleaning of a roller screen transporting and screening particles by means of at least three rotating rollers. The rollers are installed in succession at given clearances and arranged transversally in relation to the transport direction of the particles to screen a desired range of particle sizes. At least one roller changes its circumferential velocity and/or its rotational direction over time at defined time intervals for defined time periods such that for this defined time period for at least one pair of neighbored rollers one roller has a higher circumferential velocity than the other and/or both rollers roll in opposite rotational directions.
