Abstract

The invention relates to a screen grating for size-dependent separation of bulk materials, comprising a plurality of grating bars (2) spaced apart one alongside another, which form a screen surface (1) and which have a smaller dimension in the width direction (y), which runs parallel to the screen surface (1) and perpendicular to the longitudinal direction (x) of the screen grating bars (2), than in the height direction (z), wherein the height direction (z) is perpendicular to the screen surface (1) and perpendicular to the longitudinal direction (x) of the grating bars (2). To prevent clogging, it is provided that the cross section of the grating bars (2) perpendicular to the longitudinal axis (x) tapers down with increasing distance from the screen surface (1) in a first portion (9) of the grating bars (2) that adjoins the screen surface (1) such that, in this height region, the width of a gap between two grating bars (2) expands in the height direction, and that the grating bars (2) are arranged parallel to one another, more particularly in the conveyance direction of the bulk material.
