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

    01.03.2015· The Vertical Spindle Mill (VSM) is one of the most popularly used grinding devices for pulverised fuel (PF) generation in coal-fired power stations worldwide. According to published figures, coal pulverisation is an energy intensive process. Approximately 0.5–1% of gross power generation from coal fired power stations is consumed in coal grinding, or approximately 40.5–81 billion kWh per annum based on the 8.1 trillion kWh world electricity generation by coal

  • Modelling of Vertical Spindle Mills in Coal Fired Power

    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 mill
