Impact energy of particles in ball mills based on DEM simulations …
Through this, the DEM simulation results can be indirectly applied for particle breakage processes. Recent studies showed that stirred mills under a dry condition follow first-order grinding kinetics and the rate constant can be linked with impact energy [17, 18]. Similar correlations were also reported for planetary ball mills [19, 20]. This ...

PRACTICALLY all fine grinding is done in a ball mill or some modification of a ball mill. Millions of tons of material are ground each year. The cost varies from, say, a minimum of 10 c. to a maximum of 35 c. per ton. It is thus obvious that even small improvements, which may result in increased grinding efficiency, would be welcomed by mill operators. A …
