### Simulation of Size Reduction in Ball Mills and DEM

That is, unless we can describe explicitly particles breaking simultaneously as the DEM simulation evolves, we stand little chance to move towards predicting performance of these machines. 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 ...

### Mechanistic ball mill modeling - EDEM Simulation

Important advances have been made in understanding ball milling during the last 25 years or so, a great part of it owing to the widespread application of the discrete element method (DEM), which is now an integral part of several advanced ball mill models. EDEM was used in ball mill simulations containing not only the grinding media (steel balls) but also ore particles. This allowed the ...

1 Abstract: Discrete element (DE) simulation of a ball mill with a large number of particles is challenging when each 2 particle is considered. Similarity principle could be adopted to reduce the number of particles in a simulation whilst 3 still maintaining the accurate flow behaviour of particles. This paper presents a scaling relationship between 4 particle gravitational acceleration, mill ...
