CENTRIFUGAL SEPARATOR Russian patent published in 1998 - IPC

FIELD: mineral dressing. SUBSTANCE: method is designed to separate minerals with regard to density. Separator contains rotor in the form of truncated cone with perforated surface enclosed in vessel containing device providing supply and pulsation of water. Cone, in the plane of its large base, is provided with annular wall with cylindrical apron fastened on inner surface of annular wall and facing light-fraction receiver so forming drainage port. The vessel has flange, central passage of which is embraced by cone apron. Raw material is fed into rotor through hollow shaft and cone small base zone. In running conditions, heavy fraction particles settle down on conical surface and penetrate through perforations into the vessel and further into heavy fraction collector. Light fraction particles move over the surface of rotor bath and, through drainage port, escape into light fraction collector. EFFECT: improved design and efficiency of operation. 2 cl, 1 dwg
