GN Solids Control has delivered 2 sets of GNFG1440 high frequency fine screens to an overseas mining operator, expanding GN’s mining processing product portfolio built on decades proven shale shaker vibration screen technology GN separation.
Mining projects face persistent pain points in fine‑particle handling: conventional vibrating screens frequently suffer mesh blinding, poor classification accuracy and unstable throughput when processing wet fine ore, tailings slurry and coal slurry. GNFG1440 is purpose‑engineered to solve these bottlenecks. Adopting two‑degree‑of‑freedom resonance vibration principle and dual imported vibration motors, this unit delivers stable linear motion with 2‑3 mm amplitude, promoting orderly particle stratification and drastically reducing screen‑blocking risksGN Solids. It offers big size effective screening area, balancing large throughput and precise fine‑size classification performance.
Drawing manufacturing standards from GN shale shaker production, the whole screen box uses high‑strength steel and undergoes stress‑relief heat‑treatment after welding to resist deformation under continuous heavy‑duty cyclic vibrationGN Separat…. The screen deck angle can be mechanically adjusted on‑site to adapt variable ore moisture and feed characteristics. Wear‑resistant polyurethane screen panels with 28‑45 % open area are fitted as standard; normal service life can reach more than six months to cut spare‑part replacement costs. Wetted surfaces are available with polyurea anti‑abrasion coating for corrosive mineral slurry conditions.
Beyond GNFG1440 fine screens, GN provides one‑stop separation solutions including multi‑deck fine screens, decanter centrifuges, skid‑mounted slurry‑treatment packages and full ranges of interchangeable screen panels. Supported by mature FAT factory testing, pre‑sales process simulation and global after‑sales service network, GN transfers reliable vibration‑separation know‑how originally developed for oil‑gas solids‑control into mineral‑processing sectors.
This shipment marks another milestone for GN in global mining market, delivering cost‑effective and durable screening equipment for fine‑ore classification, tailings recovery and slurry dewatering requirements.
