LOW-SHEAR FEEDING SYSTEM FOR USE WITH CENTRIFUGES

摘要

A centrifugal separator (5) for solid-liquid separations comprises (a) an accelerator (10) rotatable at an angular velocity omega about an axis (18), and having an inside surface (24) with a point (26) on the axis, and (b) a nozzle (22) for introducing a feed stream at a volumetric flow rate (Q) into the accelerator via an orifice (50). The orifice is substantially centered about the point, and the orifice has an inner diameter (d) within the range of approximately 0 < d ].
