In modern thermal power plants coal grinding mills are an important and very frequent subsystem. As time passes the grinders in the mills become depleted and the functionality of these mills decreases. Because of that the mills need to be stopped periodically, every 1500 hours, so they can be checked and, if necessary, repaired. During this …
