Learn MoreBall Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†“V = 0.40 ...

Learn MoreApr 15, 2018· The positive axis point (PAP) of a bowling ball is different for every bowler. Your pro-shop operator will be able to help you find the PAP, which is the spot on the ball equidistant from every point of the ball's track. Think of it this way: there is one point on the ball that is the same distance from every piece of the oil ring around the ball.
