Modelling of vertical spindle mills. Part 1: Sub-models

2015-3-1  The vertical spindle mill is named after its drive shaft orientation. A schematic of an E-mill VSM is shown in Fig. 1. The pulveriser is air-swept in which the coal is fed onto a rotating table through a central pipe. The coal is thrown outward by rotation into the grinding race.

Modelling of vertical spindle mills. Part 1: Sub-models

A new mechanistic model for vertical 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 the model: (1) the coal specific property, and (2) the machine specific variables.
