Abstract
A separator includes a drum ejection passage control element and an intermediate ejection control element both mounted on a drum assembly. The drum ejection passage control element is moveable between a first position and a second position. In the second position a drum ejection passage is open for ejection of material from a maximum diameter of a separator volume, while in the first position the drum ejection passage control element blocks the drum ejection passage to prevent the ejection of material from the maximum diameter of the separator volume. An intermediate ejection path is formed in the separator, each extending from an intermediate ejection path inlet at an intermediate region of the separator volume to an intermediate ejection path outlet. The intermediate ejection control element is moveable to alternately open or close the intermediate ejection path for fluid communication to the separator volume.
