Balls & shot for muzzle loading gunsHornady roundballsare die swaged from pure soft lead. Eachballis perfect, no shrinkage, no sprue, no wrinkles. Hornady roundballsare made in the most popular calibers. Hand cast roundballsare cast from pure soft lead. Eachballhas a tiny flat, where the sprue was removed. Place this flat spot on top, centered on your muzzle

Effects ofBall Size Distributionand Mill Speed and Their Interactions onBall MillingUsing DEM. A comprehensive investigation was conducted to delineate the effect ofball size distribution, millspeed, and their interactions on power draw, charge motion, and balls segregation in a laboratory

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 KâˆšF

Simulation ofSizeReductionin Ball Millsand DEM. Themillwith cm in diameter and cm in length and the test conditions are standardized, with a maximumball sizeof mm and an ore topsizeof mm with less thanballs, it poses no challenge in running the simulations, if only grinding media are included for such a smallmill, one could also include the ore or powder charge
