Stone milling versus roller milling: A systematic review of the
Roller milling involves the separation of the endosperm from the bran and germ, followed by a gradual reduction in endosperm particle size (Campbell, 2007). Wheat passes through a series of rollers (rolls), accompanied by sifting between stages (Doblado-Maldonado et al., 2012). Rolls may be smooth or fluted, according to the stage of the However, they retained some advantage: running roller mills from water or wind sources required extensive gearing, which made them complex, noisy, and prone to failure.
