The ability to model comminution techniques has been key in the mineral processing
industry and other industries where size reduction of rocks is a key focus. With the need for …

In the early 1990s the discrete element method (DEM) was used for the first time to simulate
media motion in tumbling mills. Although it has been over a quarter of a century since this …

The discrete element method (DEM) has proven to be a powerful tool to simulate processes
involving particulate material. When simulating materials handling operations that lead to …

Breakage occurs in several particulate systems that are simulated using the discrete
element method (DEM), namely crushing and grinding as well as inadvertently in several …

Abstract Description of particle breakage embedded in a simulation using the discrete
element method (DEM) qualifies it to describe processes in which breakage is either desired …

This study explored the breakage kinetics of cement clinker in a lab-scale ball mill loaded
with steel or alumina balls of 20, 30, and 40 mm sizes and their mixtures. The temporal …

Particle breakage occurs in comminution machines and, inadvertently, in other process
equipment during handling as well as in geotechnical applications. For nearly a century …

Vertical stirred mills have become increasingly popular in size reduction operations in the
fine and ultrafine range, being normally used in industry in continuous operation. The …

Particle scale modelling of comminution processes can provide significant insight into the
flow of particles, their breakage, the effect of slurry, wear and energy utilisation within these …

Several approaches have been proposed in the past to describe particle breakage inside
the DEM environment. The large number of particles dealt with in most operations of interest …
