Decanter Centrifuge
High-Speed Solids Control Equipment
The Decanter Centrifuge is the final and finest stage of solids control, separating ultra-fine particles (2-15μm) from drilling fluid using centrifugal force up to 3066G. It provides precise control of drilling fluid properties and is essential for maintaining optimal mud weight and viscosity in demanding drilling operations.
CHINA KOMAL offers both Premium and Economic series centrifuges with fixed speed, VFD, and hydraulic drive options to meet various operational requirements and budget considerations.
