Water Jacket Centrifugal Concentrator in Mineral Processing

Water Jacket Centrifugal Concentrator in Mineral Processing

The Water Jacket Centrifugal Concentrator is a highly efficient gravity separation device, primarily employed in the concentration stage of mineral processing. It is specifically designed for the recovery of fine, high-density valuable minerals. This equipment excels at processing a variety of heavy minerals, including but not limited to gold, tin, tungsten, lead, iron, manganese, and tantalum-niobium ores.

It is a staple component in alluvial and hard rock gravity separation circuits. Commonly, it is integrated into placer gold washing plants, tin ore processing lines, and tungsten beneficiation flowsheets. It often operates in conjunction with equipment like sluice boxes, jigs, and shaking tables to achieve optimal recovery rates, particularly for particles in the size range below 2mm that are challenging for traditional gravity methods.

The working principle relies on enhanced centrifugal force and fluidized bed separation. The feed slurry is introduced into a rapidly rotating cone-shaped drum. Centrifugal force pushes heavier particles against the drum wall, where they become trapped in grooves (riffl es). Simultaneously, a continuous flow of low-pressure water through the water jacket creates upward fluidization, flushing away lighter gangue minerals. The combination of these forces allows for efficient separation based on specific gravity.

Its key advantages and features include:

• High Recovery Rate for Fine Particles: Exceptional at capturing micron-sized gold and other heavy minerals.

• Continuous Operation: Automated, continuous concentrate discharge improves efficiency compared to batch systems.

• Low Energy Consumption: Operates with relatively low power and water pressure requirements.

• Environmentally Friendly: Typically requires no chemicals, making it a green technology.

• Simple Operation and Maintenance: Robust design with easy-to-replace parts.

  

The main structural components are:

1. Frame & Drive System: Provides stable support and houses the motor that drives the rotating assembly.

2. Rotating Cone (Drum): The core separation element, a steel cone with internal riffl es, mounted on a vertical shaft.

3. Water Jacket Assembly: Encloses the rotating cone, supplying fluidizing water through precisely controlled nozzles.

4. Feed & Discharge System: Includes the feed pipe for slurry introduction, the tailings discharge port, and the automated mechanism for intermittent concentrate removal.

5. Control System: Manages rotation speed, water pressure, and the timing of the concentrate discharge cycle.
