In roller mills, three criteria are essential in producing a 700- to 800-micron particle size (1) the rolls should be moving with a differential drive of one roll moving 50 to 75 percent faster than the other to produce a shearing action that will help cut the kernel rather than crush it (2) the rolls should have corrugations to help slice the grain, with the desired corrugations per inch of roll being 8 to 10 for
