While the grinding aids had only a marginal effect on the grinding of quartz, they had a significantly beneficial effect on the grinding of limestone and cement clinker. Triethanolamine appeared to be the most effective of all the aids studied. In the grinding of cement clinker, gypsum also acted as a very effective grinding aid.
Cement Grinding Aid Mechanism in VRM Benefits of Cement Grinding Aid CGA reduces the inter-particle attractive forces of cement which causes agglomeration of cement grains.
IN THE CEMENT PRODUCTION ABSTRACT This is a summary of the use of cement additives 111 the cement production, focusing on the mechanism of action of grinding aids (G.A.). A distinction will be made between pure G.A. and G.A. performance enhancers, that act on the mechaniœal characteristics of the cement.
