Ball mill control -Automatic start-up control In most cement plants, start up of a mill is con­ducted through a series of manual operations on the part of an operator. The operator switches on the mill, starts the mill feed and, after as­certaining that the mill load becomes stable, changes the control mode to the constant-value feedback ...

As a result, operating costs in a cement plant will be reduced. Ball mills used in the cement industry are inefficient grinding technologies. Any small improvement in the operation of ball mills can lead to significant annual energy savings (Tiggesbӓumker and Müller, 1983, Viswanathan and Reddy, 1992, Schnatz and Knobloch, 2000). Thus, new ...
