PURPOSE:To obtain the titled apparatus having improved treating capacity compared with oscillation grading apparatus, by placing a crossing treatment cylinder at an end of a screw grading apparatus placed nearly parallel to a threshing cylinder shaft and making waste dust to be passable through the crossing treatment cylinder before discharged from the machine. CONSTITUTION:A crossing treatment cylinder 31 is placed at an end of a screw grading apparatus placed nearly parallel to the shaft of a threshing cylinder 7. All waste dust of the screw grading apparatus is passed through the treating cylinder before being discharged from the machine to recover cereal grains in high recovery. Loss of grains caused by certain maladjustment or difference in the kind of grains can be remarkably decreased by the re-treatment of the grain with the crossing treatment cylinder.
