Energy optimization in cement manufacturing
Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.
