All of these three approaches have been used for modelling compressive breakage in cone crushers. Herbst and Potapov (2004) used a version of the TEM method but only displayed results from a 2D simulation of a crusher. The TEM approach was later applied in 3D by the same group for modelling a Morgårdshammar B90 laboratory crusher (Lichter et al., 2009).
