does not correlate with the grinding performance. Also the reduction of the mechanical toughness by surfaceactive compounds (Rehbinder effect) is not verifiable. Clear evidence was found that grinding aid molecules, with their polar and nonpolar parts, compensate and reduce the polarity of the clinker surfaces to a considerable extent.

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 Indian Institute of Technology,Delhi 13 14. • If E = ve that means the energy is released and the grinding aid spreads out on clinker''s surface.
Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.
The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closedcircuit tube mill operating at ...
Grinding aids for high performance cements Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness.
