    Oct 22, 2020The 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 critical

    The most important strategy is to have good break technique. This is covered in detail on the break technique resource page and in "How to Break Like a Pro" (BD, September, 2016).. Generally, as shown below, the goal on a 9-ball break (either by breaking from the side rail or with a cut break from the "box") is to pocket the "wing ball" and squat the CB in the center of the table
