PROBLEM TO BE SOLVED: To prevent the incompleteness in grain milling and excessive grain milling by the irregularity in the grain sizes of grains with a grain milling device. SOLUTION: In the grain milling device which classifies the grains to be supplied to a grain milling chamber by the sizes of the grains prior to the start of the grain milling and mills the grains at prescribed grain milling accuracy by each of the classified grains, grain milling treatment is carried out by setting the grain milling pressure of the large-size grains greater than the grain milling pressure of the small-size grains. The grains of the large diameters having a high degree of filling are set greater in the grain milling pressure and the grains of the small diameters having a lower degree of filling are smaller, by which quality is made approximately uniform.
