摘要： A centrifugal separator provides for discharge of solids by either an axial-motion scraper or a piston/extrusion assembly. The axial-motion scraper (80) is used with hard-packed or friable solids, and includes an integral feed liquid accelerator and feed holes. The piston/extrusion assembly is used with pasty solids, and includes a piston (12) extending into a separator bowl (10) and having openings (45) permitting fluid communication across the piston. After separation is complete, a centrate valve (34) closes one end of the bowl, and the piston is moved axially in the bowl by an actuator. A bowl suspension employs a spherical mounting structure (96) and a short, spindle (98). A bearing (100) and the spindle (102) of bowl are mounted within the bearing housing. The suspension is retained by a ring and retaining member secured to the separator in compressive contact with the spherical portion of the bearing housing.
