"Improvement of mechanical strengths by the use of grinding aids: optimisation of sulphate content in cement " By Davide Padovani, Matteo Magistri - Mapei SpA, Italy Abstract A key point i n cement technology is the improvement of mechanical properties, particularly in terms of compressive strengths.
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. Organic compounds are also often added as grinding aids to avoid powder agglomeration.
The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
