Abstract

The invention comprises a roller screen 1 for separating two or more finer and coarser material fractions of wood chips from each other, in particular for separating fines fraction and pin chips fraction from the wood chips that are usable as regards chip size. On the surface of one or more of the rollers 4 of the roller screen there are substantially radial 14 and substantially axial 15 grooves, of which the axial grooves 15 are deeper than the radial grooves 14.
