3-phase Horizontal Decanter Centrifuge I

The 3-phase Horizontal Decanter Centrifuge continuously separates three phases (solid-liquid-liquid) in a single step, effectively separating two liquid phases with different densities and one solid phase simultaneously, with the solid phase being the heaviest.

This centrifuge employs an adjustable pump impeller to discharge the heavy liquid phase while the light liquid phase is discharged by gravity. The adjustable impeller enables online adjustment of the liquid pool depth and the liquid-liquid separation interface, ensuring optimal clarity of the liquids and eliminating the need for downstream equipment.

In addition to its high separation efficiency, the 3-phase Horizontal Decanter Centrifuge offers flexibility to adapt to changes in feed conditions. Furthermore, JX Filtration provides reliable process and service capabilities, ranging from project planning and commissioning tailored to specific applications, to after-sales maintenance and spare parts supply, all backed by extensive experience.

Operating Principle:

The structure and operating principle of the 3-phase Horizontal Decanter Centrifuge are similar to those of the 2-phase decanter centrifuge. Under the action of centrifugal force, solid particles settle on the inner wall of the drum, and the screw rotates at a slightly different speed from the drum, pushing the settled solid phase towards the conical end of the drum.

When using the three-phase centrifuge, the heavier liquid is discharged through the adjustable pump impeller under pressure, while the lighter liquid flows out by gravity. The pump impeller can continuously adjust the depth of the liquid pool during operation, allowing for rapid and precise adjustments based on feed conditions without interrupting operation.
