Modelling of vertical spindle mills. Part 2: Integrated models for E
There are three basic structures among the coal grinding, t: Air-Swept or Wet Tumbling Ball Mill, Roller-Race or Ball-Race Mill and Hammer or Impact Mill [7–10]. The type of the mill and its efficiency depend on the type of coal, its moisture, input and output fraction of the material and the grinding susceptibility of the coal.

Performance optimisation of vertical spindle coal pulverisers
A mill's heat balance evaluation was done using an Excel spreadsheet to evaluate the mill drying capacity constraint. Coal analysis was done on hard grove grind ability, abrasive indices and calorific value of coal. The effect of low calorific value coal was observed on mill's response to match the boiler energy requirements.
