METHOD OF REGULATION OF CEMENT PRODUCTION PROCESS IN DISCRETE CONTINUOUS MILL Russian patent published in 1998 - IPC

FIELD: manufacture of building materials; control of cement production process. SUBSTANCE: method is based on selection of energy of plain cement as adjustable parameter; energy of plain cement corresponds to activity of cement; it is taken as preset magnitude. Then energy of produced cement is measured at grinding clinker with additives after preliminary determination of energy of additives and clinker with additives. In case energy is less than preset magnitude, time of milling clinker without additives or its fraction in initial relationship of components is increased, after which additives are introduced to obtain preset magnitude of energy of plain cement. EFFECT: reduction of specific power requirements and enhanced efficiency of milling process.
