Abstract The sub-models of comminution and classification for vertical spindle mill (VSM) presented in Part 1 of this paper have been integrated in the VSM simulation models for the E-mill, MPS mill and CKP mill. Plant survey data from an E-mill (ball-race) and MPS mill (roller-race), both including internal streams and external sampling, and the CKP mill (roller-race without internal classification) were used to calibrate the VSM sub-model parameters for each device. It was found that the fitted comminution and classification model parameters were closely related to the primary air flow rates in the VSM operation. Relationships between the sub-model parameters and the air flow rates were established. Once the models are calibrated, no further model parameters fitting is required. The VSM models have been implemented in Microsoft Excel via the MDK (Model Development Kits) protocol. A number of potential applications of the JKMRC VSM models for coal-fired power stations and other industries are discussed.
