Recently the 5 sets of big bowl decanter centrifuges are shipped to overseas tailings slurry separation project.
The supply of 5 sets of big bowl decanter centrifuges for an overseas tailings slurry separation project is a systems level investment in water security, tailings risk mitigation, and operational continuity. The technical case rests on high G separation, wear engineered construction, and VFD driven flexibility; the strategic case rests on water recovery, dry stackable solids, and compliance with evolving global tailings standards. As mining jurisdictions worldwide move toward stricter tailings governance and more ambitious water stewardship targets, fleets of big bowl decanter centrifuges are poised to transition from alternative technology to standard practice in responsible tailings management. The 5 units deployment described here exemplifies that transition — not merely a shipment of equipment, but the installation of a dewatering backbone for a project that cannot afford to treat tailings as an afterthought.
Why should we use the big bowl decanter centrifuges?
Decanter centrifuges separate solids from liquids by feeding slurry into a rapidly rotating horizontal bowl, generating centrifugal forces that can reach up to 3,500 G. Denser solids migrate to the bowl wall, where an internal scroll conveyor continuously transports them to a discharge outlet, while clarified liquid exits from the opposite end. The result is a dry, stackable cake suitable for dry stacking or co-disposal, alongside clean process water that can be returned immediately to the plant.
GNLW764-VFD series big bowl decanter centrifuge is a 30m inch bowl centrifuge, which offers a bowl length to diameter ratio of 4.38 and a capacity of 60 ~ 120 m³/h for coal mine tailings, depending on feed solids content. Variable frequency drive (VFD) control systems that allow independent adjustment of bowl speed and differential speed.
