The present invention relates to a cutting ring assembly for a rice mill in which a spacing ring including at least one or more inducing protrusions is alternately disposed between cutting rings to smoothly and forcibly transfer rice grains in the direction of a discharge hole of the rice mill without damaging the rice grains. The cutting ring assembly for the rice mill according to the present invention includes a support shaft having a hollow cylindrical shape and in which at least one key groove is formed in each of an inner circumferential surface and an outer circumferential surface in a longitudinal direction, a plurality of cutting rings coupled to the support shaft, and a plurality of spacing rings coupled to the support shaft and disposed between the cutting rings. Also, the cutting rings have a ring shape having a predetermined thickness and a plurality of channel-shaped cutting passages, which connect both side surfaces of the ring to each other so that rice bran is cut while the rice grains pass therethrough, in an outer circumferential surface thereof, and a key groove connection protrusion formed in an inner circumferential surface thereof is inserted and coupled to the key groove formed in the outer circumferential surface of the support shaft. Also, the spacing rings have a ring shape having a predetermined thickness and includes at least one inducing protrusion in an outer circumferential surface of the spacing ring, and a key groove connection protrusion formed in an inner circumferential surface of the spacing ring is inserted and coupled to the key groove formed in the outer circumferential surface of the support shaft. |
