Grinding aids are organic compounds added during the grinding of clinker to prevent cement particle attraction and re-agglomeration, thus resulting in clinker and energy savings which can both lead to reduced CO 2 emissions. This paper seeks to quantify the increase in grinding mill outputs derived from the use of amine or glycol-based GA.
