In the case of ball mills, this is certainly not straightforward. Let´s consider a simple example: the most common tumbling mill test used in the lab is the Bond ball mill grindability test, used for nearly 70 years to determine the Bond work index, which is a number used to estimate how hard it will be to grind the material of interest.
The objective of this study is the development of wear models that will allow further work in process control as a function of mill wear. This study addresses theoretically the question of ball mill wear via the modelling and simulation of ball charge and liner wear.
