CFD based investigations into optimization of coal

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.

Classification performance of model coal mill classifiers

Mar 01, 2020 1. Introduction. The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles.

Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding. There is minimal metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.
