This device sorts cylindrical workpieces into three size groups: oversize, within-size and undersize (rejects). The workpieces are dumped into hopper 1 and are fed out, one by one, along chute 2, onto rotating disk 3 mounted on spindle 4. By centrifugal force the cylindrical workpieces are forced outward to the precise gap between disk 3 and ring 5. The within-size and undersize workpieces pass through the gap and along a chute to the second disk 6. The oversize workpieces are removed by a stripper (not shown in the drawing) and they drop through a hole in spindle 4 into hopper 7. The within-size and undersize workpieces are forced outward by centrifugal force to the precise gap. Only the undersize workpieces (rejects) pass through the gap and roll down the casing into hopper 8. The within-size workpieces are removed by a stripper (not shown) and drop into hopper 9.
