Decanter Centrifuge For Oilfield Drilling Mud Solids Control Weighted And Unweighted Mud Processing

Decanter centrifuge descriptions

The DAGYEE Heavy Duty Decanter Centrifuge is purpose-built for the demanding conditions of mining and mineral processing applications. Designed to handle abrasive slurries, high solids loading, and continuous operation, this centrifuge delivers exceptional performance in tailings dewatering, concentrate thickening, and mineral recovery. Its robust construction, specialized wear protection, and high-capacity design ensure long service life even in the most challenging environments, including iron ore, copper, gold, lithium, and phosphate processing.

Experience maximum solid-liquid separation efficiency

• High-performance separation, resulting in high-value products and low waste management costs
• Lower energy consumption and carbon footprint
• Minimal maintenance costs thanks to continuous operation, high-grade machine materials, smart design and well-thought preventive services
• Low capital cost/capacity ratio
• Wide-ranging feed variations and controllable performance

How does a decanter centrifuge work?

Mineral slurries are fed continuously into the high-speed bowl. The centrifugal force (up to 3000G) rapidly separates solids from liquids based on density differences. The screw conveyor transports settled solids up the conical beach for continuous discharge while the clarified liquid overflows from the opposite end.

1. Feed Introduction: Slurry enters through the feed tube into the conveyor cylinder, where it is gently accelerated to reduce particle degradation before entering the bowl.

2. High-Speed Sedimentation: Under high G-force, mineral solids settle to the bowl wall at accelerated rates. The centrifugal force is up to 3000 times gravity, enabling rapid separation of fine mineral particles.

3. Solids Conveying and Compression: The screw conveyor continuously moves settled solids toward the discharge end. As solids move up the beach, they are compressed to remove additional liquid, producing a dry cake.

4. Liquid Discharge: The clarified liquid (centrate) overflows through adjustable weir plates, with the pool depth controlling cake moisture and liquid clarity.

5. Beach Drying: The conical beach section allows additional drainage of liquid from the solids before discharge, maximizing cake dryness.
