Abstract
A suspended centrifuge apparatus has been improved by the addition of a restraint that closely maintains the original, static, vertical axis of a suspended centrifuge vessel during rotation. The restraint is preferably located to act on the lower half of the suspended vessel and preferably limits axial gyration to less than 5-degrees. A further improvement is a centrifuge bowl configuration which provides a protected surface to be acted on by a gyration restraint while partially eliminating centrifuge bowl capacity in a lower, central region subjected to inherently low centrifugal forces. An improved liquid separation process results from the use of the improved apparatus to better control the liquid discharge trajectory from the rotating centrifuge. Process control and safety are also improved.
