The contribution of DEM to the science of comminution
Nirmal Weerasekara,Malcolm Powell,Paul W. Cleary,Luís Marcelo Tavares,Magnus Evertsson,Rob Morrison,Johannes Quist,Rodrigo M. de Carvalho +7 more
TL;DR: In this article, the authors provide a general overview of the application of computational techniques to the science of comminution, including simulation of fracture, breakage, crushing, milling and equipment wear.

A new autogenous and semi-autogenous mill model for scale-up, design and optimisation
TL;DR: In this paper, a new AG/SAG mill model has been developed which incorporates the capability to respond to changes in most design and operational variables and can be used as a stand-alone design tool, to scale-up from pilot data and to optimise existing circuits.

The effect of ball size on breakage rate parameter in a pilot scale ball mill
A. Seyfi Erdem,Ş. Levent Ergün +1 more
TL;DR: In this paper, the effect of ball size on the grinding kinetics in a pilot scale ball mill was investigated, and the relationship between different breakage rate and particle size has a maximum for each ball size distribution.
Journal ArticleDOI
Modelling the performance of industrial ball mills using single particle breakage data
TL;DR: In this paper, the performance of an industrial ball mill can be adequately described using the ore-specific breakage distribution function together with the systematic variation of the material transport and the breakage rate functions with process conditions and mill diameter, respectively.
Journal ArticleDOI
Estimating energy in grinding using DEM modelling
TL;DR: In this paper, a campaign of DEM simulations were performed by varying the mill size and charge particle size distribution to explore and understand the breakage environment in mill and comminution device modelling.
