Decanter Centrifuges for Dewatering & Solids Control
Maximize Recovery. Improve Efficiency. Reduce Disposal.
If your operation demands best‑in‑class decanter centrifuges, Astec | Elgin Separation’s engineered separation systems deliver unmatched performance for liquid/solids separation, dewatering centrifuge processes, and oil & gas centrifuge applications. Built for rugged environments and heavy use, Elgin Separation technology supports zero‑discharge strategies, closed‑loop systems, and high‑throughput solids control.
With more than 550 decanter centrifuges installed worldwide, operators trust our centrifuge technology for durability, reliability, and exceptional separation efficiency across drilling, mining, industrial processing, wastewater management, and more.
What Is a Decanter Centrifuge?
A decanter centrifuge is a high‑performance mechanical separation device engineered to remove solids from liquid slurries with precision and speed. By leveraging centrifugal force, Elgin’s centrifuges rapidly separate dense solids from liquid streams — making them essential for effective solids control centrifuge and dewatering centrifuge operations.
How It Works
- The slurry enters a high‑speed rotating bowl.
- Centrifugal force drives heavier solids outward against the bowl wall.
- A concentric auger (scroll) rotates at a controlled differential speed, transporting solids to the discharge ports.
The result is two distinct outputs:
- Underflow (cake) — concentrated solids ready for disposal, reuse, or further processing.
- Overflow (centrate/effluent) — clarified liquid for reuse or discharge.
This efficient separation process helps:
- Improve mud conditioning in drilling and wellsite operations
- Reduce waste volume for disposal
- Enhance fluid quality for reuse
- Lower overall operating costs
