Abstract. Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best make-up ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range …
The Population Balance Model (PBM) was used to empirically analyze the performance of a vertical mill and a Bond ball mill. The breakage parameters obtained for both grinding mills are compared to determine the possibility of predicting the product size distribution of a vertical mill based on the results obtained from the Bond ball mill.
Differences up to 6,2% in the Bond ball mil work index can be observed due to different siz distribution in P 80 calculation.. 13 ores were tested using the Bond ball mill grindability test, obtaining P 80 using different interpolation functions. Rosin Rammler's model showed the best behavior, so its use must be not only suggested, but …
Grinding particles below 75 µm with the ball mill causes energy costs to rise exponentially, and a P 80 of 45–40 µm is considered to be the final practical limit of product size from the ball mill (Morrell et al., 1993) beyond which stirred mills are selected in current mineral processing circuit designs to produce fine particles in an ...
