CONE CRUSHER Russian patent published in 2004 - IPC

FIELD: equipment for processing of various materials. SUBSTANCE: cone crusher has bed, truncated outer cone and inner cone mounted by means of bushing and spherical bearing inside outer cone on shaft for axial and radial displacement, shaft drive, radial cone vibration shock absorber, spring-type axial vibration shock absorber and unbalancing device. Working surfaces of cones define annular wedge-shaped charging-discharge slit. Truncated outer and inner cones are oriented with their larger bases upward. Inner cone is positioned above outer cone and connected to bushing through additional spherical bearing positioned eccentrically with respect to main bearing. Unbalancing device is fixed on bushing end or on shaft console end in cone contacting zone. Multithread spiral channels on working surface of inner cone are adapted for moving products under process to outer cone. Sieves and vessels for fractions of product under process may be positioned under cones. EFFECT: increased efficiency and improved grinding quality. 2 cl, 2 dwg
