Grinding aids (GAs) are a kind of additive commonly used in cement, which can effectively reduce the energy consumption of cement research and production processes [1], [2]. It has been confirmed that the addition of GAs of 0.01 %–0.05 % by cement weight to ball mills can significantly increase the machine-hour output of cement mills [3].
This is in view to tapping the maximum benefits of using GAs in cement production and use. This review work established that GAs have a positive influence on …
Cement Additives Division ΠMAPEI Italy Effect of grinding aids in the cement industry 5 4.
