In solid-liquid separation operations across industries such as oil drilling and chemical environmental protection, the ability to process materials continuously and efficiently while maintaining stable separation results is key to increasing capacity and controlling costs. The Decanter Centrifuge (Horizontal Spiral Discharge Sedimentation Centrifuge) developed by KOSUN Machinery, with its mature centrifugal sedimentation technology and innovative structural design, has become core equipment for processing multi-medium suspensions. It plays an irreplaceable role, particularly in drilling mud purification and industrial sludge dewatering.

The core advantages of the KOSUN Decanter Centrifuge stem from precise centrifugal sedimentation principles and user-centric structural design. By leveraging centrifugal force to achieve high-efficiency separation of microscopic particles from the liquid phase, it can accurately capture and separate solid particles with a diameter ≥2μm. After processing, the mud regains its ideal viscosity and specific gravity, enabling efficient recycling and significantly reducing the cost of new mud procurement and the pressure of waste discharge.
As continuous-duty equipment, it utilizes a “Bowl-Scroll” collaborative operation mode. Once the suspension enters via the feed pipe, solid particles rapidly settle on the inner wall of the bowl under centrifugal force. They are then continuously pushed to the discharge port by the screw conveyor (scroll), while the clarified liquid phase is directed out through the overflow port. This continuous separation process requires no downtime, significantly enhancing operational efficiency.
Durability and intelligent design further highlight the product’s competitiveness. Key components of the KOSUN Decanter Centrifuge, such as the bowl and screw conveyor, are manufactured from high-quality stainless steel. Critical wear-prone areas are sprayed with tungsten carbide wear-resistant coatings or embedded with hard alloy inserts, effectively improving corrosion and wear resistance to extend service life. For complex drilling conditions, it is equipped with an explosion-proof VFD (Variable Frequency Drive) control system, allowing for stepless adjustment of the separation factor. This flexibility enables the equipment to adapt to suspensions of various concentrations, ensuring operational stability. Furthermore, the specialized adjustable overflow port design reduces energy consumption by more than 15% compared to similar products, further lowering operation and maintenance costs.
With its stable performance, the KOSUN Decanter Centrifuge is widely used in domestic and international oil drilling, coal chemical industries, and more. In overseas drilling projects, its explosion-proof design and multi-medium adaptability meet the stringent operational standards of different regions. The processed drilling waste consistently meets local environmental discharge requirements, making it one of KOSUN Machinery’s flagship products for international market expansion. From onshore oilfields to industrial wastewater treatment sites, this equipment provides customized solutions for solid-liquid separation needs with its hallmarks of “High Efficiency, Stability, Reliability, and Energy Saving.”
