PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL

The mill is designed to handle a total ball charge of 324.5 t at 100% loading with a percentage filling of 29.5% in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber.

The ball charge and ore charge volume is a variable, subject to what is the target for that operation. The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the total charge.
