Introduction The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles.
Vane almost exclusively refers to a piece of metal that spins on an axis, like a weather vane. The homophone vain is typically an adjective meaning "prideful" or "conceited," but is also heard in the phrase in vain, meaning "tried without success" or "pointless." Lastly, vein often refers to tubes that carry blood, and in the same vein is a ...
