A bowl feeder for separating damaged rolling bodies, for example nuclear fuel pellets, from sound ones includes a bowl (10) having a central conical section (12) for distributing the bodies radially outwardly towards a V-shaped circular channel (16) which ensures that the bodies are arranged end-to-end with the rolling axes orientated lengthwise of the channel. The channel (16) discharges the bodies one by one onto an outer sloping section (14) whose slope is sufficiently shallow to allow bodies with asymmetrical defects to resist rolling by virtue of the shift in their centres of gravity, while allowing defect free bodies to roll radially outwardly down the slope. A system of rails (22, 24, 26) with gaps (28, 30, 32) serves to separate defective bodies from those which are defect free, the latter being allowed to roll to the outer periphery of the bowl and eventually to a feed track (38) while the former are routed to a reject outlet (40).
