FOUNDATION ENGINEERING CHARACTERISTICS OF THE . for a mill with a ball and rod load. Cheek calculations for vibrations of 10 foundations of ball and rod milis installed at five mining and concentration plants and a comparison of the results obtained with the actually measured amplitudes of Calculate Ball Mill Grinding Capacity 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 divergent.
