PROBLEM TO BE SOLVED: To obtain a grain milling device which can spring out the grain intruding from the spacings between grinding rolls. SOLUTION: A grinding type grain milling roll 30 arranged in a grinding type grain milling treatment section is constituted by laminating a plurality of annular grinding rolls 100 and spacers 112 for forming the spacings 120 are disposed at 90 deg. intervals between the grinding rolls 100 which are adjacent to each other in an axial direction. Accordingly, when the grains come to intrude from the spacings 120 while the grinding type grain milling roll 30 rotate integrally with a rotating spindle 20, the grains are sprung out by curved hypotenuse parts 112B of the spacers. |
