Method of Steel Grinding Ball Proportioning and Example,

28/08/2021· Method of Steel grinding ball proportioning. The method of ball distribution for a ball mill can be summarized as follows: 1. Take all the ore samples from a ball mill (usually take new ore and returned sand samples, then match the samples in proportion) for sieving analysis. Divide them into several particle sizes, such as 18-12, 12-10, 10-8,
