The invention concerns a new process for manufacturing milled corn products such as flour, semolina, middlings and similar, in which the material is repeatedly ground between rolls and sieved by the high grinding technique. According to the new development proposed, the grinding material is fed at least twice through double roll grinding stages (70) without sieving betwen the stages, and the mill product of each stage is then sieved (152). A suitable new mill with at least two double milling passes and designed preferably as an 8-roll set (70) is preferably used. The new mill preferably has a combination of eight- (70) and four-roll sets (142, 151). For the double grinding, the sieve surface is at least 20 to 50 % greater than that used for single grinding. |
