horomill horizontal roller mill principle. Apr 24, 1997 Abstract: Comminution is an important element for cost evaluation in any cement plant, mainly in relation to the power consumed, which is about 80 to 90 kW for a cement plant. In the early 90s, grinding in cement plants was operated mainly by vertical mills for raw material with rather ...

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 ...
