Coals used for power plants normally have different ash contents, and the breakage of coals by the ballandrace mill or roller mill is an energyintensive process. Grinding phenomena in mill of power plants is complex, and it is also not the same with ideal grinding tests in labs. The interaction among various coals would result in changes of grinding behaviors and energy consumption ...
