Sep 18, 2013 The cement mill certificate includes three performance tests that merit close attention false set, Vicat setting time and strength. False set. False set is the tendency for cement mixtures to stiffen early, typically due to the sulfate in the cement reacting with the water to form gypsum crystals over the first few minutes of mixing.
The challenge in identifying a cement ball mill process is irregular sampling of cement fineness (Blaine). The online sensor for measuring of fineness is usually a costly method and it is not suitable for mass production. Hence, it is imperative that
