III. Main Product Types

1. Classified by usage function

   • Classification hydrocyclone: Used for classifying coarse and fine particles in ore grinding circuits to achieve closed-circuit grinding.

   • Desliming cyclone: Removes fine mud impurities from ore pulp and improves the grade of concentrate

   • Concentration cyclone: Concentrates and dewaters tailings slurry to reduce moisture content

   • Heavy medium cyclone: Used for heavy medium separation of coal and ores to recover dense medium.

   • Desanding cyclone: Removes coarse sand particles from ore pulp and sewage, protecting subsequent equipment

2. Classified by combination form

   • Single hydrocyclone: Suitable for small flow rate and simple classification working conditions

   • Cyclone group: Installed in parallel combination of multiple units to meet the demand for large flow and large-scale production

3. Classified by lining material

   • Polyurethane-lined hydrocyclone: wear-resistant and corrosion-resistant, suitable for conventional slurry working conditions in mines

   • Wear-resistant ceramic lined hydrocyclone: Suitable for high-hardness, highly abrasive coarse-grained materials

IV. Product Performance Characteristics
