Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

Portland cement Wikipedia. Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker The materials in cement clinker are alite, belite, tricalcium aluminate, and tetracalcium

Re: Low temperature cement grinding. Hi Gio, Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills, the mill outlet temperature is around 8085 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution. This will help to increase the strength. Raj. Reply
