Mud Decanter Centrifuge

Mud Decanter Centrifuge

TR Decanter Centrifuge is a horizontal decanter centrifuge for solid-liquid separation in drilling fluid and drilling waste treatment. Centrifugal force removes suspended solids from drilling mud during continuous operation.

As a drilling mud centrifuge, it serves oil and gas drilling, drilling waste management (DWM), HDD mud recycling, and geothermal drilling. In DWM systems, it can be installed downstream of a vertical cuttings dryer. It removes fine particles from recovered fluid and returns reusable mud to the treatment system.

Different bowl sizes and drive configurations cover different feed capacities and process requirements.

Working Principle

Feed slurry enters the rotating bowl through a stationary inlet tube. A feed rotor accelerates the slurry to bowl speed before it reaches the separation zone.

Centrifugal force drives suspended particles toward the bowl wall to form a sediment layer. The screw conveyor and bowl rotate in the same direction at different speeds. This differential speed moves the settled material toward the tapered end for discharge. Clarified liquid flows toward the opposite end and exits through adjustable overflow ports.

Advantages of Solids Control Centrifuge:

• High-capacity bowl: Large internal volume for high processing capacity.

• High centrifugal force: Effective removal of fine suspended particles.

• Duplex 2205 stainless steel: Main bowl and collection housing.

• Wear-resistant conveyor: YG6 carbide plates, long service life.

• Replaceable discharge protection: Carbide rings or ceramic inserts.

• FAG or SKF bearings: High-speed continuous operation.

• Three-stage overload protection: Mechanical, hydraulic, and electrical protection.

• Siemens and Schneider components: Industrial electrical components.

• Flexible feed pump options: Progressive cavity screw pump or centrifugal pump.

• Optional VFD: stepless bowl-speed adjustment.

Decanter Centrifuge Technical Parameters

New Materials

The main bowl and collection housing use Duplex 2205 stainless steel. Compared with 316L, it offers higher strength and better resistance to chloride pitting and stress-corrosion cracking, making it suitable for corrosive drilling fluids.

Replaceable ceramic inserts protect the solids discharge outlets. The main unit and gearbox covers are made of stainless steel.

Applications of Drilling Centrifuge

• Oil & Gas Drilling

  Fine solids removal and barite recovery in drilling fluid solids control systems.

• Drilling Waste Management

  Treatment of recovered drilling fluids, including systems downstream of vertical cuttings dryers.

  
  

• HDD Mud Recycling

  Removal of accumulated suspended solids from recycled drilling mud after primary solids control equipment.

• Geothermal Drilling

  Drilling fluid recovery and suspended solids removal in geothermal drilling operations.

• Other Industrial Applications

  Solid-liquid treatment in coal washing, mineral processing, tailings dewatering, and industrial wastewater treatment.

Selection Guide

Choose the model according to feed capacity, fluid properties, solids concentration, particle size, and the required treatment result.

Bowl and differential speed depend on the target, such as fine particle removal, liquid clarification, or barite recovery. Feed pump selection depends on slurry characteristics and flow rate.

For model selection, provide feed capacity, fluid density and viscosity, solids concentration, particle size, separation target, barite recovery requirement, and available power supply.

FAQ

• What is a drilling mud centrifuge used for?

  It removes suspended solids from drilling fluid and can also support barite recovery and liquid clarification.

• How do I choose the right model?

  Selection depends on throughput, mud properties, treatment target, and available installation space.

• Which feed pump is suitable?

  A progressive cavity pump suits viscous mud, while a centrifugal pump suits lower-viscosity fluids with suitable solids content.

TR manufactures decanter centrifuges for oil based mud treatment and drilling waste treatment. Model and configuration are selected from the actual feed rate, fluid properties, and site conditions. Feed pump and control configuration can be matched to the process requirements.
