    The roller mill minimizes such costs by precisely reducing feed materials with an average particle size up to 3⁄ 4 inch to a uniform average size typically between 100 and 2,000 microns. The roller mill’s ability to reduce materials to a uniform particle size provides more control of product characteristics and minimizes waste, as shown in
