Full-Text Paper (PDF): Use of cement grinding aids to optimise clinker factor. Cement production has been much increased all over the word since the early 1950s, especially in developing countries [1]. This industry is considered as a one of the top high energy consumption industries [2] . A considerable part of this

Mar 17, 2017 Considerably more effort has been expended in developing grinding aids for dry grinding systems than for wet grinding systems. Most of this work is oriented toward the cement industry, where huge amounts of cement clinker are dry ground in ball mills. Cement clinker is particularly difficult to grind, and the

Nov 26, 2015 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

Grinding aids have been used successfully for dec- ades in cement production and many other areas, such as ceramics, pigments etc. The main effect is to reduce energy consumption and increase the grinding efficiency. Additional features can be improved – e.g. powder flowability and strength development of binders.
