## Modelling Of Vertical Spindle Mills In Coal Fired Power Plants

A mathematical model of a vertical spindle mill used in coal-fired power plant is presented. the model is developed based on a mill size mass balance (smb) and mill global mass and energy balances. the model has been validated using data collected from a 660 mw unit during mill modelling field tests. the model can be used to perform mill dynamic performance studies, design and evaluate new.
