The raw meal preparation process of the cement industry includes four links: mining, pre-homogenization, grinding, and homogenization, which form the homogenization chain of raw meal preparation. Raw meal homogenization is the most important process link of the four, accounting for 40% of the homogenization task.احصل على السعر
Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen contentاحصل على السعر
