Quality control of raw materials blending in the cement industry

Abstract:

Quality control of the slurry in the cement industry is based on weight ratio control of raw materials. Raw materials composition is usually assumed constant and know due to difficulties in direct measurement. In this case study a raw materials mill control, developed and implemented in a factory is presented. The composition control involves three different steps: i) prehomogeneization beds modeling to forecast the mill input composition, ii) estimation of the past mill input composition from actual output analysis and iii) mill output control. Major emphasis is placed on parts i) and iii).
