  • Cement Clinker Quality Control During Clinker

    Generally speaking, the fineness of the raw meal needs to be contained between 12% and 16% to ensure the quality of the product clinker. If the raw meal fed to the kiln is too coarse, it will increase the heat load of the kiln, decrease the decomposition rate of the raw meal during the calcination process, and the solid-state reaction in the kiln will not be completely done, which will reduce the quality of finished clinker.
