The drilling fluid centrifuge, typically a horizontal decanter centrifuge, serves as the final stage in solids control systems, removing 2-7μm particles from drilling fluids.
▌Applications & Performance
- Non-weighted mud systems: Removes solids >2μm missed by desanders/desilters
- Weighted mud systems: Controls viscosity by eliminating colloidal particles
Three centrifugal configurations:
- Low-speed (500-700G): 1600-1800rpm for barite recovery
- Medium-speed (800G): 1800-2200rpm for viscosity control
- High-speed (1200-2100G): 2200-3000+ rpm for ultra-fine separation
▌Technical Advantages
- SS304/316 construction
- Hard-faced scroll components
- Precision dynamic balancing
- Modular maintenance design
- SKF/FAG bearing systems
- Dual-motor configurations
