ABSTRACT:
A method and apparatus for separating particles preferentially accelerates particles to a rotating collector, which then reliably conveys collected particles to a discharge with minimal re-entrainment of the particles in the fluid stream. The collector minimizes energy transfer to the fluid and maximizes separation under conditions of high particle loading, fine particle content, or both. The separator may be operated in any vertical, horizontal or oblique orientation, or within devices whose orientation varies over time.
