sitic transformation occurs, and for 12 mJ m 2 < SFE < 35 mJ m 2, mechanical twinning takes place. To estimate SFE variations in this work, the thermodynamic model described by Allain for the FeMnC system [5] was used. The term DGex was incorporated into the model to include the effect of grain size on SFE in austenitic steels, as studied by ...

Whiten, 1974, Broadbent and Callcott, 1956 later presented crusher models utilizing this approach, applied to both cone crushers and mills, In today's literature the models are either described in summation form or using matrix multiplication, where Evertsson et al. (2000) used the later for his mechanistic cone crusher model.

The BPM method has previously been applied for modelling of breakage in cone crushers by the authors in a series of publications (Johansson et al., 2015, Quist and Evertsson, 2016, Quist and Evertsson, 2010, Quist et al., 2011). The BPM model is implemented on clusters of sub-particles assembled with the shape from 3D scanned …

A model for cone crushers was presented by Evertsson (2000). That model comprises a flow model and a size reduction model. The Evertsson flow model is based on mass balance and it has a single model parameter. A particle is released at the top of the mantle. Three modes of motion can occur: sliding, free-fall and squeezing.
