A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and
Full text of Holderbank Cement engineering book On the other side the fineness at the mill outlet depends mainly on the time the material remains inside the mill, also called retention time. The main factor influencing the retention time is the mill length. Therefore, the ratio of length to diameter of a mill is an important factor for an
Time delays are especially with Vertical Mills very low, as the retention times of the raw material inside vertical mills is only some minutes. In ball mills the retention time is longer, however much shorter than in ball mills used for cement grinding, as the fineness of the raw meal is lower than of finish cement.

Daniel pointed out the critical influence of gypsum dehydration to anhydrite on cement performance low mill exit temperatures and short retention time will reduce dehydration to anhydrite, which may mean that an increased amount of gypsum is required in the final cement blend, or additional anhydrite.
