Decanter Centrifuge Technology

Decanter centrifuges offer continuous, high-capacity solid–liquid separation by exploiting differential centrifugal forces. Our horizontal scroll-discharge designs achieve g-forces up to 4,000 × g, making them ideal for dewatering sludges, classifying minerals, and recovering valuable solids.

With adjustable pond depth, differential speed, and conveyor pitch, our decanters adapt to varying feed characteristics without mechanical modification. Wear protection on scroll flights, beach, and cylinder sections extends service life in abrasive applications such as mining tailings and drilling mud.
