01/04/2013· The chemical grinding stabilizers that are linked up to the surface groups of cement particles resulting from the clinker grinding process participate in the hydration process. The rate of hydration is one of the key variables in the application of grinding additives in the cement industry. 3.
Cement additives are mainly dosed onto the clinker belt close to the inlet of the mill. Frequently, the clinker is hot and parts of the cement additive evaporate as can be seen in Figure 1. Therefore, good ventilation must collect the evaporating gases and/or respiratory protective equipment should be used.
ractical experiences with all major cement producers around the world show that stronger grinding additives enhance cement particle dispersion. Besides higher production rates, this also results in more favourable particle size distribution PSD which physically accelerates strength development and allows for higher clinker replacements.
