AIR SEPARATORS

The dust laden air swept from the ball mill flows upward into the bottom of the separator cone. As the air (gas) rises, it flows between the inner and outer cone until it reaches the inlet vanes. ... Second the air velocity inside the inner cone is kept high for best separator efficiency. Demopolis only bleeds air in when making TIII or high ...

Air Swept Coal Mill

The air-swept ball mill has a similar structure to the ordinary mill, but the input size and the output size are less, and most of the power of the material is supported by wind. The air-swept coal mill is a critical component in coal-fired power plants and industrial furnaces.
