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.
