GRINDING TECHNOLOGY COURSE - The Cement Institute

It is necessary to grind clinker, gypsum, and sometimes other additives in the proportions required at a predetermined fineness in any cement grinding circuit. The fineness is usually defined by the cement’s specific surface area measured in m²/kg or cm²/g. High-efficiency separators are usual to grind cement in a closed-circuit system due to energy consumption savings.

Cement mill - Wikipedia

Efficient closed-circuit systems, ... have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance. High ...
