Definitions

  • FIG. 1 shows by way of example a form of construction of an improved cyclone dust classifler according to the invention in axial verticalsection.
  • a cylindrical body having a tangential inlet through which a gaseous fluid containing the solid particles to be classified enters said body, and an upper outlet communicating with suction means and a lower outlet for discharging the largest particles
  • a secondary tangential inlet below said first named inlet an inverted frustroconical deflector having its upper and outer edge secured to said body below said first named inlet and above said secondary inlet and extending downwardly and inwardly past said secondary inlet to direct a blast of material entering therethrough, said deflector having a free lower end forming a central passage for air and material, and an annular horizontal deflector attached to the wall of said body substantially opposite the free end of said .frustro-conical deflector, and disposed to reduce the space between the narrow end of said frustro-conical deflector and said body whereby to increase the whirling speed of air entering through said secondary air inlet.
