A roller mill acts more like a cutting knife. As one roller spins against another, it creates a shearing effect. Roller mill particle size generally sees lower variance than hammer mills, which results in a more consistent grind. Hammer mills also use different screen sizes to adjust the particle size for either a coarser or finer grain.
