>Silo - an overview | ScienceDirect Topics
Traditionally, ball or tube mills are used in finish grinding, but many plants use vertical roller mills. In ball and tube mills, the clinker and gypsum are fed into one end of a horizontal cylinder and partially ground cement exits the other end. Modern ball mills may use 32–37 kWh tonne − 1 for cements with a Blaine of 3500.
>AVAILABLE AND EMERGING TECHNOLOGIES FOR …
Grinding of clinker, together with additions of approximately 5 percent gypsum to control the setting properties of the cement can be done in ball mills, ball mills in combination with roller presses, roller mills, or roller presses. While vertical roller mills are feasible, they have not found wide acceptance in the U.S. Coarse
