Variable Frequency Decanter Centrifuge: Efficient, Intelligent Mud Treatment

The DC355-VFD High-Speed Decanter Centrifuge System brings together multiple components into a single integrated solid-liquid separation solution. Designed for drilling mud, chemical suspensions, and environmental sludge, it pairs a DC355-VFD horizontal centrifuge with a 60m³ mud tank, agitators, and a slurry pump. Together, these elements form a closed-loop treatment system built for efficient, automated operation. KOSUN delivers this advanced centrifuge system engineered for high-performance solids control.

Key Features of the DC355-VFD System
1. High-Efficiency Separation

With a drum speed of 3900 RPM and a separation factor of 2033 , the centrifuge achieves rapid, precise separation of solids and liquids. Its filter-free design prevents clogging, making it well-suited for oily, viscous, and fibrous materials such as petrochemical sludge.

2. Durable and Energy-Saving Design

The hard-alloy screw conveyor doubles wear resistance, extending service life in abrasive conditions. Meanwhile, dual variable-frequency motors recover auxiliary motor energy, cutting power consumption by approximately 10% .

3. Intelligent Mud Tank System

The 60m³ tank features an anti-settling design, automatic level and density detection, and remote feed control via electric actuators. Motors are IP55 and ExdBT4 rated, ensuring safe operation in harsh field conditions.

4. Compact and Environmentally Friendly

A fully enclosed structure prevents leakage and contamination, while the compact footprint fits easily into constrained drilling sites.

Operational PrincipleMud is pumped into the centrifuge, where centrifugal force separates solids and liquids. The processed mud achieves optimal density and viscosity for reuse, while clean fluid is automatically transferred to downstream systems. This enables continuous recycling and energy efficiency
