Modelling of vertical spindle mills. Part 1 Sub models

Mar 01, 2015· Abstract. A new mechanisticmodelforvertical spindle mills(VSM) has been developed by Julius Kruttschnitt Mineral Research Centre (JKMRC) at the University of Queensland. Unlike the previous work in the literature, which treats the VSM as a “black box”, the present work incorporates two sets of variables in themodel: (1) thecoalspecificproperty, and (2) the machine specific variables.
