Mill (grinding) – Wikipedia, the free encyclopedia. To calculate the needed grinding work against the grain size changing three half-empirical models are used. …SAG mills use a ball charge of 8 to 21%. … »More detailed

For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles; therefore, the size at which the S value becomes maximum, x m , increases as the ball size becomes larger.

In the ball mill, measurement by MCP resulted in a charge level of 27.0%. The measurements conducted with S width presented a wide variability, with an average of 30.7% that could be between 27.9 and 34.2 with 90% confidence.

Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered, it is recommended that ball mills be ground out prior to shutdown for measurement of the charge level.
