USA - Classifier vane for coal mills - Google Patents

Sep 01, 2009· The major classification takes place in the classifier, which is located at the top of the mill housing. The air/coal mixture enters the classifier through angled vanes, which impart a swirl to the flow. Coarse particles impact on the wall, are trapped and are returned (7) to mix with the raw coal (8) on the rotating table.
