GN GNLW764 Large‑Bowl Mining Decanter Centrifuge Ready for Shipment

GN Solids Control’s  GNLW764A-inch (760 mm) decanter centrifuge has completed full assembly, water running test and factory acceptance inspection, and is fully prepared for shipment to a large‑scale overseas mining project. As GN’s largest‑capacity T‑series dewatering decanter centrifuge, this model is purpose‑built for high‑throughput solid‑liquid separation for mining tailings, quarry slurry, TBM tunnel mud, dredging slurry and industrial wastewater treatment.

Per official product specifications, the GNLW764A features a 760 mm bowl diameter and 3160 mm bowl length, with length‑diameter ratio of 4.2:1. Under 20 % feed solid content, its designed throughput reaches 120 m³/h (528 GPM). It delivers max G‑force up to 2900 G, typical working G‑force 0‑2060 G, and can capture fine particles down to 2‑5 μm. The differential speed ranges 5‑28 RPM, supported by heavy‑duty gearbox with 25000 N·m torque. Main motor options cover 110 / 132 / 160 kW and back‑drive motor 22‑90 kW for flexible site configuration.

The bowl and screw conveyor adopt duplex stainless steel for anti‑corrosion performance. Critical wear‑prone zones including slurry distribution ports, solid discharge outlets and screw blades are protected with tungsten carbide hard overlay, resisting continuous abrasion from hard mineral particles and greatly extending service life for abrasive mining conditions. Different from ordinary industrial centrifuges, GN performs high‑speed dynamic balancing for bowl and screw under actual working rotating speed. All core components are precisely machined on GN’s in‑house high‑end CNC lathes and gantry milling machines, guaranteeing stable round‑the‑clock continuous operation and lowering unplanned downtime. Equipped with full VFD‑PLC‑HMI control system, operators can independently adjust bowl speed and differential speed. The system supports real‑time monitoring for vibration and temperature to adapt variable feed slurry properties, balancing solid cake dryness and clarified liquid quality.

After separation, discharged solid cake can achieve around 30 % moisture content. Clarified water can be recycled onsite for production, cutting freshwater consumption, sludge transportation cost and helping mine operators comply with strict local environmental regulations for tailings storage and wastewater discharge.

GN Solids Control’s core competitive advantage lies in complete in‑house R&D, mechanical processing, assembly and testing capability for decanter centrifuges, with multiple separation‑technology patents. Our full‑range portfolio includes T‑series dewatering, Y‑series separation, C‑series clarifying and LWS three‑phase centrifuges.

CBM Drilling 5 Stage Solids Control System for India Drilling Company

 

GN Solids Control recently com pleted the manufacturing and factory acceptance test of a 5 stage solids control system, which will be shipped to an Indian drilling contractor for their CBM Drilling project. This engineered mud processing package is purpose-built to handle coalbed methane drilling mud, efficiently separate drilled solids, maintain stable mud density and reduce overall operational cost for on-site drilling operations.

The customer from India focuses on coalbed methane exploration and production. In CBM Drilling operations, fine coal particles and rock cuttings easily contaminate drilling fluid. Without reliable solids removal, the mud properties will deteriorate rapidly, bringing high wear risk to drilling rig pumps and downhole tools. After comparing multiple global suppliers, the Indian team selected GN Solids Control as their partner for this mud recycling package, relying on our rich field experience in coalbed methane drilling fluid treatment.

5-stage Configuration for CBM Drilling Mud Treatment

This complete system adopts a five-stage solids removal sequence. The first phase is shale shaker for primary coarse cuttings separation. The subsequent hydrocyclone units remove medium-sized solids, followed by a vacuum degasser to eliminate gas entrained inside the drilling mud, which is critical for CBM applications with frequent gas influx. The final stage uses decanter centrifuge to strip ultra-fine solids, to keep the mud within target parameters for continuous drilling.

All mud tanks, pipelines and supporting skids are fabricated according to international drilling standards. The modular skid-mounted design allows fast site assembly and disassembly, suitable for frequent rig movement in remote CBM drilling sites across India. Every unit passes strict pressure and function testing before delivery, to minimize on-site commissioning difficulty.
