Decanter Centrifuge :- The Concept
The centrifuge is a rotating assembly that uses centrifugal force to separate solids from liquids. The materials fed into the centrifuge each have different specific gravities which allow them to "settle" concentrically at different levels in the rotating assembly of the centrifuge. The material with the higher specific gravity (solids) will settle on the inside wall of the rotating assembly, while the lighter material (liquids) remain towards the core of the rotating assembly. The internal conveyor (scroll) which is rotating at a slightly different speed moves the settled material up the "beach" of the conical end of the machine towards the discharge ports. Solids are compacted and dewatered by the centrifugal force and released through these ports. Used liquids from the process are released at the opposite end of the machine through adjustable weir plates. |
