Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

But when something like roller wear, coal grindability and moisture content variation, or mill blockage, happens, the coalgrinding dynamics will be altered. This changes the coalgrinding residence time. The mill may then be driven beyond its capability and be runback to its minimum speed due to very high mill dP (Fan and Rees, 1994a). .
