    Feb 20, 2005The Whiten perfect mixing model approach was used for the ball mill modeling. This method considers a ball mill, or a section of it, as a perfectly stirred tank. The process can be described in terms of transport through the mill and breakage within the mill. The model is expressed as a size mass balance of the mill content and the breakage
