The cement grinding is an energy intensive process. The addition of grinding aid during the process of cement grinding, results in improvement of the specific surface and grind-ability of the material ground. This is attributed to the additive’s ability to reduce resistance to comminution and to prevent agglomeration of the freshly ground particles (due to neutralization of static charges) and powder

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
