Cement. Grinding aids have been traditionally used to improve the efficiency of the cement maturation process which is considered as one of the most energy consuming processes in cement production (60 - 70% of the total electricity consumed in the plant). They are usually added at the entrance of the mill together with the feed.
Grinding aids were first commercialized approximately 40 years ago to improve the fineness of the cement and increase the production rate. Grinding aids are liquid solution formulated as water-based solutions of organic compounds with high charge density, such as glycols, esters of glycols, alkanolamines or carboxylates of alkanolamines.
