Diamond Core Drilling operations demand precse solids control to maintain drilling fluid quality and protect expensive core bits. GN Solids Control, a leading manufacturer of solids control equipment, recently delivered a specialized hydraulic drive centrifuge unit to an Australian exploration client. This shipment underscores the company’s growing presence in the Asia-Pacific region and its capability to deliver tailored solutions for remote drilling operations.
Full Hydraulic Drive Centrifuge Technology
At the core of the supplied system is the GNLW223D-FHD Hydraulic Drive Centrifuge, engineered specifically for diamond core drilling applications. Unlike traditional electric-driven models, this unit operates entirely on hydraulic power, making it ideal for integration with drilling rigs already equipped with hydraulic systems. The centrifuge achieves a cutting point of 2–5 microns and delivers a processing capacity of 50–100 GPM, effectively removing ultra-fine solids that would otherwise accelerate bit wear and reduce core recovery quality.
The full hydraulic drive configuration provides independent, continuous control over both bowl speed and scroll differential speed. Operators can adjust parameters in real time to match changing mud conditions, ensuring optimal separation efficiency across varying drilling formations. The bowl rotates at speeds up to 3400 RPM, generating sufficient G-force to separate fine solid particles from the drilling fluid slurry. Key wear components—including the screw conveyor with tungsten carbide tile protection and solids discharge ports with tungsten carbide inserts—are built for extended service life in abrasive drilling environments.
Complete Solids Removal System Configuration
The Australian package includes a comprehensive solids removal unit designed for trailer-mounted deployment. The system features a 6 m3 mud tank with a compact skid structure, allowing easy transport between exploration sites. Two GN40ZJL-25-FHD feeding and discharge pumps handle fluid circulation, while a GNSLD-260 mixing hopper supports rapid mud preparation when new drilling fluid is required. Additionally, two mud guns are installed to prevent solids settling and maintain uniform mud properties within the tank.
Driven by a diesel-hydraulic power unit generating 40 kW total power, the entire system operates independently of grid electricity—a critical advantage for remote exploration locations across the Australian outback. The centrifuge processes drilling fluid directly from the drill collar, separating drill solids from the mud slurry before returning clean fluid to the active system. This closed-loop configuration reduces water consumption, minimizes waste disposal volumes, and ensures consistent mud weight and viscosity throughout the drilling program.
GN Solids Control Commitment to Australian Market
With established operations through GN Solids Australia, the company provides local technical support, spare parts inventory, and after-sales service to clients across Australia and New Zealand. All diamond core drilling centrifuge units undergo rigorous factory testing before shipment, and field commissioning support is available upon request. GN Solids Control continues to expand its product portfolio for the exploration drilling sector, offering scalable solutions from single centrifuge units to complete multi-stage solids control systems tailored to specific project requirements.
