scale up of power consumption in agitated ball mills

Scale‐up of power consumption in agitated ball mills ...

Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.

Accurate Scale Up - IsaMill™ Advantages Isamill

Power scale up is accurate because power is measured as power consumption at the agitator shaft to determine the specific energy requirements and size the mill; and PSD scale-up is accurate because of the horizontal IsaMill™ layout, which eliminates any short circuiting, and the classifying action of the product separator.
