Clinker production. As shown in Fig., the feedstock first enters the raw material to make a fine powder (raw feed), where 85% of the material is slightly smaller than 88 μ, the feed is transferred to the homogenizing silos to impair the material difference. After that, the meal is thrown into the precalciner tower to start the chemical change to cement.
