Claims

[Scope of utility model registration request]

An upper cyclone is formed between the inner cylinder and an outer shell surrounding the inner cylinder, a secondary classification chamber is formed inside the inner cylinder, and the upper cyclone and the secondary classification chamber are connected via guide vanes. A disk is fixed to the upper part of a coarse downcomer tube which communicates with the inner cylinder and extends downward from the lower end opening of the inner cylinder, and a primary classification chamber having an air supply port is formed above the disk. A lower cyclone is formed around the downcomer, and the same classification chamber and the lower cyclone are communicated via an annular flow path formed between the disk and the outer shell, and a tertiary cyclone is formed above the upper cyclone. A dry classifier characterized in that a classification chamber is formed and a rotating plate having classification blades is disposed in the tertiary classification chamber.
