The energy efficiency of ball milling in comminution
To illustrate how grinding conditions can affect ball mill efficiency, the batch grinding model will be used to model closed-circuit ball milling of the soda-lime glass. For this model, the size range of a particulate assembly in a batch mill is divided into size intervals with a maximum size X 1 above and a minimum size X n+1.
