FIELD: process engineering.SUBSTANCE: invention relates to fine grinders to be used in metallurgy, chemical industry, etc. Proposed mill comprises vertical cylindrical housing with inner circular ledge and shaft aligned with said housing. Cup-like rotor is arranged on said shaft and furnished with hub, horizontal section arranged above said circular ledge and bent from the center, screens and through slots at bottom above rotor inclined surface composed of rectangles. Every larger side of said slots is located at rotor inclined surface. Perforated cylinder is mounted aligned with the housing to form finished product discharge chamber with housing surfaces and circular ledge. Vertical cylinders are mounted above the rotor and aligned with cylindrical housing to form circular chambers. Radial ribs are arranged in rotor cup. Side of every radial rib facing the rotor hub is arranged between vertical cylinders. Vertical cylinder bottom parts are inserted in the rotor. Rectangular slot is made at radial rib top part to receive large vertical cylinder.EFFECT: higher yield of preset-size product, higher efficiency.3 cl, 2 dwg |
