OSTI ID:7294655

The potential for energy conservation in the cement industry is assessed. Chapter 1 covers projected energy requirements and examines the long-run growth patterns that will influence cement markets in Europe, Japan, and the U.S. Chapter 2 contains schematic process and flow diagrams and deals with the major steps required to produce a finished portland or modified portland cement from natural mineral deposits or industrial by-products. The discussion is divided into three steps: raw material preparation; pyroprocessing; and finish grinding and end uses. Chapter 3 deals with raw material preparation for manufacture of portland cement. Chapter 4 concentrates on pyroprocessing, production and energy consumption by process. Chapter 5 discusses finish grinding and treats divergent properties of raw materials with respect to grinding. Chapter 7 discusses alkali reactivity and by-product gypsum. Chapter 8 deals with energy-saving technology, that is, through use of preheaters, precalciners or major kiln modification or replacement. (207 references) (GRA)
