of 80mm. The raw materials are mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill). The vertical roller mill grinds the marital to D 85 of 90µm. The ground product is calcined in a preheater to 850900℃. After calcination, the materials enter to a rotary kiln and heated to 1450℃ to become clinker.
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 ...
