Identical mixes containing fixed amounts of ordinary Portland cement clinker and gypsum were ground in two types of industrial cement mills—viz. ball mill (BM) and vertical roller mill (VRM)—to identical Blaine fineness to examine the effect of any possible differential comminution of gypsum on cement setting times.
The dehydration of gypsum in the cement mill was simulated in the laboratory by grinding clinker with gypsum to form cement, and then dehydrating the gypsum by heating the cements for various periods.
Why Differential Pressure Is High In Grinding Mills. Generalized Predictive PID Controller of Differential Pressure in Vertical Roller Mill for Cement-Raw Grinding NING Yanyan 1,2, YUAN Mingzhe 1, WANG Zhuo 1 Derivation and validation of a coal mill.Cement grinding operation may be performed in one of the following mill setups.
The method of grinding cement may also influence the hydration kinetics. Cements ground in high pressure roller mills set faster than in ball mills, because of higher reactivity of C 3 A and C 3 S phases, and a lowered rate of decomposition of …
