GN 30-inch Bowl Diameter Decanter Centrifuge for Domestic Mining Slurry Concentration Application

GN Separation officially launches its newly upgraded 30-inch large-bowl decanter centrifuge, specially customized for high-concentration mineral slurry thickening and dewatering in domestic mining projects. Breaking the limitation of small and medium-size centrifuges with low single-unit throughput, this large-diameter separation equipment delivers high-efficiency solid-liquid separation for metal ore, non-metal ore tailings slurry, coal washing slurry and mineral concentrate dehydration, providing an energy-saving, high-yield and fully automatic solution for domestic mining enterprises to realize tailings dry stacking and resource recycling.

Severe Pain Points of Traditional Mining Slurry Treatment in Domestic Mines

In recent years, domestic mining industry has raised stricter standards for tailings environmental treatment, resource recovery and production efficiency. Most medium and large mines adopt traditional thickener pools matched with small-size decanter centrifuges to treat mineral slurry, which bring multiple production bottlenecks:
  1. Low single machine processing capacity: Small-bowl centrifuges cannot cope with the massive slurry output of large-scale mines, requiring multiple units to work in parallel, leading to high equipment investment and complicated pipeline layout;
  2. Poor adaptability to high-concentration slurry: Fine mineral particles with high specific gravity are hard to be fully intercepted by conventional equipment, resulting in high water content of discharged solid tailings and low recovery rate of mineral concentrate;
  3. High operation and maintenance cost: Mining slurry contains a large number of hard rock particles with strong abrasion, ordinary centrifugal vulnerable parts wear rapidly and need frequent replacement, which affects continuous mining production;
  4. Large energy consumption and low automation level: Old-fashioned fixed-speed centrifuges cannot adjust operating parameters according to real-time slurry concentration, resulting in unnecessary power waste and relying on manual on-site operation for a long time.
In addition, the land occupation of tailings ponds is increasingly restricted by national environmental policies, so mining enterprises are in urgent need of large-capacity, high-dehydration-efficiency separation equipment to realize dry discharge of tailings and reduce the storage pressure of tailings ponds.

Core Technical Advantages of GN 30-inch Large Bowl Decanter Centrifuge

The 30-inch bowl diameter is the core design highlight of this model. Compared with conventional 22-inch, 26-inch centrifuges, the effective settling area inside the drum is greatly expanded, which prolongs the sedimentation time of mineral particles and significantly improves slurry treatment capacity and separation precision. Combined with targeted mining-oriented structural optimization, the equipment has prominent industry advantages:
  1. Ultra-large processing capacity to match large-scale mining production

    With a 30-inch integral forging rotary drum and optimized length-diameter ratio design, the maximum hourly processing capacity of mineral slurry reaches 80-120 cubic meters, which can replace 2-3 sets of medium-sized centrifuges. It simplifies the on-site layout of the slurry treatment system and reduces the overall investment of supporting facilities such as feeding pumps and pipelines for mine owners.

  2. High-strength wear-resistant structure adapted to abrasive mineral slurry

    The main drum is made of thickened duplex stainless steel, while the conveyor spiral surface is overlaid with tungsten carbide wear-resistant alloy. The slag outlet, feeding port and other flushing parts are equipped with replaceable high-chromium alloy bushings. Even under long-term continuous treatment of hard ore slurry such as iron ore, copper ore and coal gangue, the service cycle of vulnerable parts is increased by more than twice, cutting frequent shutdown maintenance losses for mines.

  3. Full-range VFD intelligent frequency conversion control system

    The complete set of variable frequency drive system realizes stepless independent adjustment of drum rotating speed and differential speed. Operators can adjust equipment operating parameters in real time according to slurry concentration, particle fineness and solid content of different ores. Whether it is concentrate thickening or tailings dehydration, the machine can maintain the optimal separation state, effectively reduce moisture content of solid slag and improve the recovery rate of useful minerals. The frequency conversion design cuts comprehensive energy consumption by 18%–25% compared with fixed-speed large centrifuges.

  4. Closed fully automatic operation, meeting domestic environmental protection standards

    The whole machine adopts fully sealed structural design to avoid slurry splashing and dust overflow during operation, without secondary pollution to the mine production area. Matched with GN self-developed PLC centralized control cabinet, it supports real-time remote monitoring of operating current, vibration, temperature and feeding flow, realizing unattended automatic operation and greatly reducing on-site labor configuration.

Practical Application Benefits for Domestic Mining Projects

After trial operation in multiple domestic iron ore and coal washing plants, the 30-inch large bowl decanter centrifuge achieves remarkable economic and environmental benefits:
  1. Mineral concentrate recovery rate increased by more than 12%, effectively improving mine resource utilization and economic output;
  2. Water content of discharged tailing slag stably controlled below 18%, dry slag can be directly transported for comprehensive utilization such as mine backfilling and building aggregate processing, greatly reducing the occupied area and safety risk of tailings ponds;
  3. Recycled clear water after separation can be fully returned to the ore washing production line, saving mine fresh water consumption and lowering water supply cost;
  4. Single machine covers large slurry treatment demand, simplifies the mine solid-liquid separation workshop layout and reduces the later equipment maintenance workload.

Market Prospect

The launch of GN 30-inch large bowl mining decanter centrifuge further enriches GN’s domestic mineral slurry separation product line. At present, GN’s full series of mining centrifugal separation equipment has been widely applied in coal washing, ferrous metal mining, non-ferrous metal mineral processing, rare earth ore and other domestic mining fields.
Facing the domestic mining industry’s general trend of green transformation, tailings dry discharge and intelligent production, GN Separation will continue to iterate large-size high-efficiency separation equipment, provide customized integrated slurry thickening and dehydration system solutions for domestic mining enterprises, and help the high-quality and low-carbon development of China’s mining industry.
