Optimization of mill performance by using

Optimization of mill performance by using

dynamics in the mill gives very valuable information to the operator. The evolution of media angle (βynamic) could probably help the operator to optimize the mill efficiency (plan a liner change and/or change mill speed if possible). Studying the complete evolution of the media angle (βynamic) through the liner lifetime can lead to an ...
