Cement - Extraction and processing - BritannicaBest energy consumption - International Cement Review

Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary Some deposits are mined by underground methods Softer rocks such as chalk and clay can be dug directly by excavatorsIn addition, the absence of the heat generated in a ball mill and the high volume of air required by the vertical mill have required the provision of waste heat from cooler exhausts and/or auxiliary furnaces to dry raw materials and achieve a limited dehydration of gypsum.

Manufacturing - the cement kiln - Understanding CementCement mill - Wikipedia

The milling process generates heat and excessive mill temperatures are undesirable It is clearly helpful, therefore, if the clinker is cool as it enters the mill From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials From a cement .A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cementMost cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
