The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely …
This finding was not effected by different ball charge filling ratios and different mill throughput mass flows. Quite typical are the results shown in Fig. 1 in which the mass-specific surface area (Blaine) and the residues on the 32-, 63- and 90-μm screens of meter-samples are plotted against the grinding path length.
