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

Coal Mill an overview ScienceDirect Topics

The rotational speed of the vertical spindle mill affects the operating conditions of the grinding unit. At high rotational speeds, the grinding unit operates at high flow of the material in the radial direction and low layers of the material under the grinding elements (balls, rollers). This causes the particles to be discharged without
