  • Modelling of Vertical Spindle Mills in Coal Fired Power

    29-08-2020· 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
