But some cement manufacturers refuse to use grinding aids for economic reason. Locher and von Seebach [5] investigated the use of organics in cement dry grinding and found that the use of chemical additives does not affect the breakage of coarse material and become a factor when fine material builds up in the mill. This conclusion was inMasterCem product family encompasses an extensive range of grinding aids,performance enhancers and specialty products. These additives are specially formulated to greatly improve the performance parameters of cement by increasing production efficiency and quality, while at the same time minimizing costs.Cement grinding aids additives MasterCem GCC / Gulf Region

Grinding aid additives for dry fine grinding processes Part II
1. Introduction. In various dry fine grinding applications, so-called grinding aids (GAs) are added to the feed material or directly into the mill either to a) increase the production capacity, b) reduce the specific energy demand, which is required to obtain a certain product quality, or c) achieve finer material or a better performance of the The history of grinding aids in dry fine grinding processes starts in the late 1930s with the application of the first commercial grinding aids in the cement industry [1]. Since that time, the importance of grinding aids in industrial dry fine grinding processes has strongly increased; so did the number of scientific papers dealing with this Grinding aids for dry fine grinding processes ScienceDirect
