rameters such as the degree of cement fineness, characteristics of clinker, grind-ing media, temperature, and humidity. A grinding aid is essentially an organic compound active in the gaseous phase which adsorbs onto the cement particle surfaces during grinding.
Grinding aids for VRMs increase the powder flowability of the finished cement without reduction of the stability of the material bed. The impact of grinding aids depends strongly on the fineness of the cement: The higher the surface area, the bigger the attraction force and therefore the bigger the benefit from an appropriate grinding aid.
May 11, 2015· • The surface energy of the clinker covered with grinding aid(E) is the algebraic summation of E1,E2 and E3. E= E3 + E2 + E3 11-05-2015 Indian Institute of Technology,Delhi 13 14. • If E = -ve that means the energy is released and the grinding aid .
