Roller Mill vs. Hammer Mill | RMS Roller-Grinder
A roller mill acts more like a cutting knife. As a roller spins, 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.
