Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the ...
The use of a good Cement clinker grinding aid can be vital in today's increasing material demands. Along with the obligation to process increasingly larger quantities of ores containing finely disseminated minerals, our limited energy resources and the rising costs of energy present a challenge to the process engineer. One research route that has been explored for about half a century is the ...
cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding .

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

Cement raw material has been almost exclusively ground in roller mills (vertical airswept grinding mills) since the second half of the 20th century. Loesche was and is the pioneer 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 six ...
Metallurgical ContentRAW CEMENT GRINDINGWET VS DRY Grinding of CementCLINKER GRINDINGCement Grinding MillsHigh Efficiency Cement Grinding Mill The principle of Grate Discharge grinding is nearly universally adapted in the cement grinding industry. Grate Discharge Ball Mills are the rule rather than the exception. Rod Mills for raw and finish grinding begin to enter the picture.
The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill's modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills .
Cement Ball Mill. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores. Cement ball mill is not only suitable for overflow grinding.
