At some point, higher levels of limestone would require such an extended amount of ball mill grinding time and would need such a high fineness, that the additional energy output would result in little to no energy reduction, and greatly affect the workability and finishing characteristics. Also, limestone is not a cementitious material.

71· For the ball milling, the breakage characteristics of a given ore were determined via drop-weight tester based on the elements. Then the model structure was developed by using the perfect mixing approach. As conclusion, the model of the whole grinding circuit can predict the element behaviours prior to the stage of concentration.
