ABSTRACT:
A classifier for powdery material has a cylindrical casing formed at an upper portion thereof with an inlet port for introducing the material to be classified into the casing in a tangential direction of an inner wall thereof. The casing has a conical portion formed in its bottom end with an opening connected to a discharge pipe for discharging coarse particles. Further, an outlet pipe protrudes into the casing through its top. The inlet port is located higher than the bottom end of the outlet port. An externally-driven vane wheel is provided under the outlet pipe in a concentric relationship with respect to the casing.
