The raw mill is either a Ball mill with two chambers or Vertical roller mill with inbuilt classifier. The hot gases from the pre heater enter the mill and are used for drying material in the mills. ... The hot gas and dry fine ground material are fed to the mill outlet to a separator, which separates the fine and coarse. The second, called ...
sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding plant must therefore be shockresistant and equipped with a number of explosion relief valves. From the raw coal silo, the feed is extracted and conveyed in enclosed equipment.
