More than a half of the energy consumed for cement production is used for grinding process of clinker (38%) and raw material (33%). In order to decrease the greenhouse gas emission, it is critically important to reduce the energy used for comminution.
FOR CEMENT RAW MATERIAL Loesche
Cement raw material has been almost exclusively ground in roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two, three, four and sixCement Types Portland Cement Association,What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.

Cement Extraction and processing Britannica
Cement 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 excavators.Industrial versus Laboratory Clinker Processing Using,Table 4 summarizes the properties of control cement and those containing GAs that resulted from industrial grinding after reaching stable conditions (the Ec values are also given). It is to be noted that the data reported in Table 4 are averages of 3 to 4 measurements collected

Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic
Best energy consumption International Cement Review
For cement grinding, the technology development away from ball mills has taken a different route. The development of roller presses in the 1980s took advantage of the benefits of higher-pressure grinding and many presses were retrofitted to ball mills as pregrinders. A typical comparison of three competing technologies is given in Table 1Overtaking cement grinding process limitations to reach,Cement activation potential becomes fully accessible for many cement grinding processes with existing limitations. In a ball mill closed circuit with first generation separator, different strength enhancers are compared (Table 1) with regards to grinding process performance.
