Comprehensive understanding of grinding aids

Mostly adsorption of grinding aids is revers-ible. As the binding forces are small at the usual mill operating temperatures (80-120 °C), adsorbed molecules can desorb from the clinker surface. The boiling points of liquids correlate with the inter-molecular interactions (“strength of the adsorption of molecules on one another”). If the liquids are chemically similar, the strengths of adsorption on
