Grinding of coal to this level of fineness is referred to as coal pulverisation. 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.
Adding biomass to coal for co-fired power generation has become widely implemented practices in order to meet the emission regulation targets. These have impacted the coal mill and power plant operation safety and reliability. The Vertical Spindle mill model was developed through the authors' work before 2007.
