Investigation of flow dynamics of porous clinkers in a

1/12/2019· The grinding time, fineness of the cement particles and uniformity in their size will depend upon mean residence time and axial dispersion of the clinkers within the ball mill. For an efficient operation, the solids/clinkers in a ball mill are expected to stay for a specified residence time depending upon holdup and flow rate, and flow with minimum axial dispersion. This implies that the mill
