1. Characteristics of Cement Raw Meal Calcination The calcination of cement raw meal is a complex high-temperature heterogeneous reaction process, with reactivity influenced by multiple factors: Raw material properties: Physical characteristics, geological origin, and mineral composition. Raw meal properties: Fineness, chemical composition, particle size distribution, homogeneity, and modulus values. During high-temperature calcination, the intrinsic properties […]
