IN AN ABRASIVE TYPE VERTICAL GRAIN MILLING MACHINE (1), THERE ARE MOUNTED, ON A MAIN SHAFT (5) EXTENDING GENERALLY VERTICALLY AND DISPOSED ROTATABLY IN AN UPRIGHT BRAN-REMOVING CYLINDER (41), A SCREW ROLL (32) FOR FEEDING GRAIN, A PLURALITY OF ABRASIVE MILLING ROLLS (23) DISPOSED BELOW THE SCREW ROLL (32) IN SPACED RELATION TO EACH OTHER ALONG THE MAIN SHAFT (5) FOR ABRADING THE GRAIN, AND A ROTARY ROLL (17) DISPOSED BELOW THE PLURALITY OF ABRASIVE MILLING ROLLS (23) FOR SENDING OUT THE GRAIN HAVING BEEN ABRADED TO A GRAIN DISCHARGE PORTION IN SUCH A MANNER THAT THE PLURALITY OF ABRASIVE MILLING ROLLS (23) AND THE ROTARY ROLL (17) ARE LOCATED WITHIN THE BRAN REMOVING CYLINDER (41), A GAP DEFINED BETWEEN THE ABRASIVE MILLING ROLLS (23) ADJACENT TO EACH OTHER FORMING A JET-AIR SLOT (31), THE BRAN-REMOVING CYLINDER (41) BEING COMMUNICATED WITH A GRAIN SUPPLY PORTION AT AN UPPER END THEREOF AND WITH THE GRAIN DISCHARGE PORTION AT A LOWER END THEREOF. A LOWER PART OF THE BRAN-REMOVING CYLINDER (41) IS EXTENDED DOWNWARD SO AS TO FACE HORIZONTALLY TO THE ROTARY ROLL (17). FURTHER, THE ABRASIVE TYPE GRAIN MILLING MACHINE (1) HAS AN AGITATING PROJECTION (18) PROVIDED ON AN OUTER PERIPHERAL SURFACE OF THE ROTARY ROLL (17) FOR AGITATING THE GRAIN HAVING BEEN ABRADED, AND THE ROTARY ROLL (17) HAS A JET-AIR HOLE (19) THROUGH WHICH JET AIR IS SENT TOWARD THE GRAIN BEING AGITATED BY THE AGITATING PROJECTION (18).
