CEMENT GRINDING AID COMPOSITION Dow Global
Grinding aids lower the amount of energy and time needed for grinding by increasing the efficiency of the grinding process. The reduced energy consumption can significantly improve the overall cost efficiency of a cement plant, for instance by reducing the operating costs of the plant, increasing cement production throughput, and/or reducing
US6241816B1 Method of treating cement Google Patents
A method of treating cement clinker by grinding the clinker in a tubular mill while charging water, gypsum, and, optionally, also a water-reduction agent to the mill at the same time. The water has a pH of from about 9 to about 13. A microfill agent and/or a water-reduction agent is mixed with said the high pH-value water to form a slurry, which is added to the clinker during the grinding

Effect of clinker grinding aids on flow of cement-based
2014-9-1 Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes, including static yield stress (τ 0) and viscosity (η).Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness.
