DEM simulation of the flow of grinding media in IsaMill

Numerical investigation of granular flow similarity in rotating drums

“…This is consistent with the common viewpoint that the general characteristics of granular flows in most circumstances are not sensitive to variations in Young's modulus when it is sufficiently large (typically beyond 1.0 × 10 9 N/m 2 ). In fact, a much smaller Young's modulus is usually adopted to considerably increase the time step in simulations (Yang, Jayasundara, Yu, & Curry, 2006;Dong et al, 2013). Additionally, the results in Fig.…”

Prediction of coupled particle and fluid flows using DEM and SPH

“…It has also been used for modelling of axial flow in ball mills (Cleary, 2006(Cleary, , 2009b and generally for understanding performance in tumbling mills (Djordevic, 2003(Djordevic, , 2005Kalala et al, 2008;Powell et al, 2011). It has also been used for modelling of stirred mills Yang et al, 2006;Jayasundara et al, 2008) A recent review of the use of DEM in comminution science is presented by Weerasekara et al (2013). DEM has also been used to predict size separation of dry particulates on vibrating screens (Li et al, 2003;Cleary, 2004;Cleary et al, 2009;Dong et al, 2007Dong et al, , 2009).…”

Computational prediction of performance for a full scale Isamill: Part 1 – Media motion and energy utilisation in a dry mill

“…This consists of a horizontal grinding chamber with central agitator containing a series of parallel grinding discs. Yang et al (2006) first studied the flow of grinding media in a simplified 1.4 l laboratory scale Isamill with multiple discs using DEM. Jayasundara et al (2006Jayasundara et al ( , 2008Jayasundara et al ( , 2010Jayasundara et al ( , 2011aJayasundara et al ( ,b, 2012 then used this model to study the effect of media properties and geometry on grinding performance and disc wear.…”
