DOI: 10.1007/s10035-019-0912-8
Abstract: The subcritical growth of intra-particle cracks and their consequent rupture are often cited among the processes responsible for creep in granular solids. However, classical testing procedures do not involve measurements of grain size distribution, thus… read more here.

DOI: 10.1016/j.mineng.2020.106210
Abstract: Abstract Current tests for characterising rock breakage in comminution do not allow decoupling of rock breakage properties from the machine environment. Furthermore, it is difficult to predict the comminution behaviour of different ores or how… read more here.
