1. Introduction. Scale-up of mills is a critical issue in designing industrial grinding circuits. Predicting the performance of a full-scale mill, such as product size and power draw based on the data from lab or pilot scale mills is a challenging task as the changes of grinding variables in the scale-up process need to be considered properly.

Typically, grinding media are not accelerated to the tip speed of the mill. Different studies reveal that the minimum grinding media tangential velocities are in the range of 30 to 50% of the tip speed [[49], [50], [51], [52]].Hence, there are several approaches to account for this effect by using specially defined factors [1, 53].Stender et …
