Screen, in particular pressure screen

Abstract

A screen (S1-S14), in particular a pressure screen or a pressure screen device which has an inlet (Z) and at least one axially spaced accept (Ak) and reject (R), is provided. Screen elements (2) are arranged in the inlet space (ZR) of the screen (S1-S14) and in the inlet space (ZR) of the screen elements, spaced radially therefrom, there is a rotor (3) which rotates by means of a driving means (G). In the axial direction between the inlet (Z) and accept (Ak), the rotor comprises at least two rotor regions (A, B) which rotate at different rotational speeds. Each rotor region (A, B) is assigned a corresponding screen basket region (2A, 2B, 2′A, 2′B). These rotor regions can rotate in the same direction or in opposite directions. The screen is operable according to the inflow principle or the outflow principle, optionally also in combination.
