ABSTRACT A sizing screen provided with feeder means for causing an even distribution of material onto the screen surface. The feeder means comprises a generally spirally shaped plough which urges material over the edge of a generally circular table the distribution of material being substantially uniform over the edge. The plough has a compaction zone for compacting the material so that urging forces exerted by the plough are not absorbed in the material. A chute which can be stepped feeds material onto the table through the plough. - 1 -
