GN Solids Control is a specialized industrial equipment manufacturer focused on designing and building solids-liquid separation systems and drilling waste management solutions。The company operates globally with headquarters in China and a significant subsidiary in the United States。
A High G (High-Gravity) Drying Shaker is a specialized equipment for drilling waste management. Its primary function is to “dry” drill cuttings by applying intense vibration (up to 8 times the force of gravity) to recover more drilling fluid and significantly reduce waste volume.
How a High G Drying Shaker Works
It is typically fed by a screw conveyor carrying wet cuttings from primary separation equipment-1. The high-G vibration forces trapped liquid through fine screens. The recovered fluid is sent to a centrifuge for further purification before returning to the active mud system, while the dried, stackable solids are discharged for disposal.
Key Benefits and Offshore Applications
The main benefits include recovering valuable drilling fluids (reducing new fluid costs) and transforming cuttings into a drier, more manageable waste that is cheaper and more environmentally compliant to handle.
For demanding offshore platforms, GN packages these shakers into integrated “High G Shale Shaker Modules.”. These modules combine the shaker with mud tanks, pumps, agitators, and an intelligent control system into a single, compact solution designed for space, weight constraints, and harsh marine environments.
In the oil and gas industry, an agitator (or mud agitator) is a mechanical device installed in drilling fluid (mud) tanks to keep solids in suspension and ensure the fluid mixture is uniform. It prevents settling and maintains consistent fluid properties, which is crucial for efficient operation.
How It Works & Key Functions
An agitator uses an electric or hydraulic motor mounted on the tank to drive a propeller shaft at a controlled speed. The angled propeller blades create a strong flow pattern that circulates the entire tank volume.
Its core functions are to:
Prevent Solids Settling: Continuous agitation stops heavy solids (like barite) from sinking to the tank bottom, which could cause blockages.
Ensure Homogeneity: It blends newly added chemicals, fluids, or weight material evenly throughout the tank for consistent fluid density and properties.
Aid in Conditioning: It helps shear and break down polymers and other additives for full effectiveness.
Key Technical Specifications
For selection and operation, important specifications include:
Motor Power: Typically ranges from 3 HP to 20 HP per agitator, depending on tank size and fluid viscosity.
Shaft Length & Propeller: Sized for the specific tank depth and diameter; often a two-blade marine-type propeller.
Propeller Placement & Speed: Proper placement is key to avoid dead zones. Speed is adjustable for different fluids.
Sealing System: A robust mechanical seal is vital to prevent fluid leakage along the shaft.
GN Solids Control Agitators
As a major manufacturer, GN Solids Control offers a range of agitators. Their models feature:
Modular Design: Allows for different motor power (e.g., 7.5 kW/10 HP) and shaft lengths.
Heavy-Duty Components: Use Italian OLI brand vibration motors and high-grade steel shafts.
Efficient Propeller: Designed for optimal flow with minimal dead corners.
Robust Seal: A high-quality mechanical seal to ensure long-term, leak-free operation.
In summary, the agitator is a fundamental, workhorse component of any drilling fluid system, ensuring reliability and consistency. Its proper operation directly impacts drilling efficiency, safety, and cost.
