Settling Thickener serves as core equipment for industrial solid-liquid separation. It achieves slurry concentration and clarification based on the gravity sedimentation principle and can process suspended slurry with medium to high solid concentrations. Its application scenarios span heavy industry, light industry and environmental governance, with the mining industry representing its largest and most widely adopted market. In mining operations, the equipment can be deployed for ferrous-metal, non-ferrous-metal and non-metallic mines alike. It is primarily used for concentrate thickening and tailings dewatering in mineral processing flowsheets. After ore crushing, grinding, flotation and other wet beneficiation processes, large volumes of water-bearing ore slurry are produced. The Settling Thickener enables fast sedimentation and concentration of fine mineral particles within the slurry, raising concentrate slurry concentration to reduce workload for subsequent filtration and drying. Meanwhile, it concentrates tailings slurry to recycle process backwater, drastically cutting mine water consumption. It is essential equipment for mine water conservation, tailings dry stacking and paste backfilling.
The metallurgical industry is another key application field, covering steel smelting as well as copper, aluminum, zinc and other non-ferrous metal smelting. Steel manufacturing produces blast furnace granulation water and converter dust-removal mud. Suspensions containing metallic waste residues can be clarified and concentrated by the Settling Thickener. Separated clean water can be recycled for equipment cooling and dust suppression spraying, while concentrated sludge can be reprocessed to recover residual metals and realize secondary resource utilization. In non-ferrous metal smelting, leaching and washing procedures generate smelting slurry. Solid-liquid separation via the Settling Thickener purifies metallurgical feed liquor, improves finished product purity and reduces raw material losses.
The chemical industry has segmented application scenarios, suitable for inorganic salt chemistry, fine chemical manufacturing and fertilizer production. Chemical manufacturing generates large quantities of crystal slurry and reaction-residue suspensions, such as phosphate and potassium fertilizer slag slurry, titanium dioxide and calcium carbonate washing slurry. Settling Thickener concentrates and clarifies such chemical slurry. Isolated clean mother liquor can be recycled into production, and concentrated solid materials can be further processed into finished goods or disposed of safely. It effectively addresses challenges including difficult solid-liquid separation of chemical slurry and severe wastewater pollution.
The environmental wastewater treatment sector has seen the fastest application growth in recent years. It mainly treats industrial wastewater, municipal sludge and river dredging sludge. Wastewater from various factories contains abundant fine suspended impurities that cannot be discharged directly. After sedimentation and concentration by the Settling Thickener, the supernatant can be reused or discharged once it meets discharge standards, and the underflow concentrated sludge achieves significant volume reduction, lowering costs of subsequent filter pressing and solidification. During river regulation and engineering sludge removal, it rapidly thickens sludge slurry to realize mud-water separation and boost dredging efficiency. Besides, sand-washing mud treatment in building materials and coal slurry concentration in coal washing are also mainstream application scenarios.
