Simulation of Size Reduction in Ball Mills and DEM

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 mill (with 30 cm in diameter and 30 cm in length) and the test ...
