GRINDING TECHNOLOGY COURSEThe Cement Institute
In any cement grinding circuit it is necessary to grind clinker gypsum and sometimes other additives in the proportions required at a predetermined fineness. The fineness is usually defined by the specific surface area of the cement measured in m²/kg or cm²/g. With high-efficiency separators it is normal to grind cement in a closed
