Effect of Ball Size and Ball to Powder Ratio Variation on
The variation of ball size in a planetary ball mill (PBM) was studied in terms of its effect on the specific impact energy of balls as a result of ball to ball and ball to vial collision calculated through a computer simulation. The mean crystallite size of calcium carbonate in the course of milling as well as the required time for obtaining a thoroughly formed calcium carbonate was also

Usually, the balls filling rate about 40%, the mill balls size are initially 30–80 cm diameter but gradually wore away as the ore was ground. In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity.
Why use Different Size Balls in a Mill
Table of ContentsOptimum Size of BallsTests with Different Mixtures of Balls in Conical, Cylindrical, and Grid MillsClosed-Circuit Grinding Several years ago, Davis assumed that the rate of wear of the different sizes of balls in a ball mill was directly proportional to the weight of each ball, and he evolved a formula for calculating a balanced charge. Operators have used this formula when

Jul 05, · The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
