    Oct 22, 2020 The mill speed is one of the vital parameters in ball mills, which is normally specified as a fraction of critical speed. It determines whether the load behavior is predo-minantly the cascading regime, the cataracting regime or the centrifuging regime. In general, the industrial ball mills rotational speed operates at 70%~80% of criticalof 12.7mm x 31.8 mm. The ball mill classification circulating load design basis was 230%.
