A sorting device to separate powdered material, esp. cement, into fine and coarse particles, consists of a main body(2) and a hopper (3) attached under the main body. The main body consists of a powder-air mixt. inlet (4) fixed tangentially to the main body, a fine particle exit(6) formed at the center of the main body, a rotating axis (7), a rotating plate(8) to disperse and separate the powder, and guide blades to introduce the powder-air mixt. into the inside of the main body.
