Effect of jar shape on high energy planetary ball milling

As an alternative to extensive experimental testing, deemed as expensive and time consuming to the point of being most often unfeasible, a dynamic mechanical model of planetary ball milling was adopted to fine tune milling parameters and establish correlations with the end product. This model, based on a simple contact scheme depending on a few easily estimable parameters, supplies quick and
