Abstract

The invention relates to a screen, provided with a plurality of rotatable screening members, which are spaced transversally with respect to the proceeding direction of the material to be screened, designed for the fine screening of material. According to the invention the screening members (3, 21, 31, 32) are in cross section essentially deviant from circular form, in order to achieve essentially vertical and horizontal motional components for the material to be treated on the screen (2, 20); and that the screening members (3, 21, 31, 32) are mutually installed so that the screen aperture (11, 27) formed by two adjacent screening members (3, 21, 31, 32) can be kept essentially in the same size throughout the screening process.
