Sep 01, 1998 Introduction. Energy utilization during the grinding process of Portland cement clinker and gypsum can be significantly improved by adding polar organic compounds referred to as grinding aids in concentrations less than 500 ppm .Because of their highly polar nature, grinding aid compounds preferentially adsorb on surfaces formed by the fracture of electrovalent bonds i.e., Ca-O and Si-O.
A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
