FIELD: process engineering.SUBSTANCE: invention relates to machine building, particularly, to two-product separators and may be used in construction, chemical metallurgical industries, etc. Proposed classifier comprises outer cylinder-taper casing with cover. Said casing is shaped to funnel with outlet. It has fine fraction and airflow discharge pipe arranged atop casing cover and coarse fraction discharge pipe arranged at casing bottom. Inner cylinder-taper casing with minor-taper cover with its vertex directed upward and coarse fraction discharge pipe arranged at casing bottom. It comprises blades with mechanism of fixed turn about horizontal axis arranged regularly between cylindrical sections of outer and inner casings. Besides, it has initial material and air feed pipe arranged at bottom of outer casing. Cylindrical parts of inner and mix casings have circular pockets. Rotary vanes have their sides located in said pockets.EFFECT: higher separation efficiency.1 dwg |
