In drilling operations, shale shakers are the first and most critical stage of solids control, separating drill cuttings from drilling fluid. A key factor affecting their performance is G force (gravitational force), which determines how efficiently the shaker removes solids.
KOSUN, a leading manufacturer of drilling fluid solids control equipment, designs high-performance shale shakers with optimized G forces to maximize separation efficiency while ensuring equipment durability.

Understanding G Force in Shale Shakers
What Is G Force?
- G force (or “G-factor”) measures the acceleration of the shale shaker’s vibrating motion relative to Earth’s gravity (1G = 9.81 m/s²).
- A higher G force means stronger vibration, improving solids separation but also increasing wear on the shaker.
Typical G Force Range
- Most shale shakers operate between 4G to 7G.
- KOSUN’s shale shakers are engineered for adjustable G force, allowing operators to balance separation efficiency and machine longevity.
Why G Force Matters in Solids Control
- Better Separation Efficiency
- Higher G forces (5G-7G) improve fine solids removal, crucial for weighted mud systems.
- Lower G forces (4G-5G) are suitable for delicate screens or lighter drilling fluids.
- Screen Life & Equipment Durability
- Excessive G force can damage screens and increase maintenance costs.
- KOSUN shakers use precise vibration control to extend screen life while maintaining performance.
- Adaptability to Drilling Conditions
- Different formations (e.g., hard rock vs. soft clay) may require varying G forces.
- KOSUN’s variable-frequency drives (VFDs) allow real-time G force adjustments.
