Homogenization is the important process in cement dry production line, and it is also the last link in the process of raw meal preparation, well homogenization not only improves clinker quality, but also has great benefit for thermal regulation stability, running rate and output of kiln improvement, energy consumption reduction.

Homogeneity and stability of raw meal have a significant influence on the quality of clinker calcination, so the quality of raw meal is the important process for raw meal preparation. After crushed and before ground, although the raw material has been prehomogenized, the fluctuation of chemical composition narrows down. Homogenization is done very well, the chemical composition have a great fluctuation because of equipment error, operation factors in the process of blending, its homogeneity and stability cannot meet the requirement of raw meal control index, so raw meal must be homogenized in the process of cement production line. At present, homogenization technology of dry cement production line is widely applied and speed development in the process of cement production, it has formed raw meal homogenization system coexist with raw meal grinding.
