Cement MillingUnderstanding Cement

As part of the grinding process calcium sulfate is added as a set regulator usually in the form of gypsum (CaSO 4.2H 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling including spraying water inside the mill. In the closed-circuit system the mill product is classified in a separator in a fine fraction that is then taken to the next stage and a thick fraction that is returned to the mill for subsequent milling. In any cement grinding circuit it is necessary to grind clinker gypsum and sometimes other additives in the proportions required at a
