Hydrocyclone

Hydrocyclone is a classification equipment that uses centrifugal force to accelerate the settling of mineral particles. Pressure feeding is required, which consumes a lot of power, occupies a small area, is cheap, has a large processing capacity, high classification efficiency, and can obtain very fine overflow products. It is mostly used in the second stage closed circuit grinding.
Product introduction
Product Overview
CATHAY hydrocyclone adopts the centrifugal separation principle and is specially designed for pulp classification/concentration/de-sludge. The separation accuracy is 0.025-0.15mm, the processing capacity is 20-800m³/h, and the underflow concentration is ≥65%. It is suitable for the efficient separation needs in metal mines, sand and gravel plants, chemical industry and other fields.
Core advantages
✅ Micron-level classification
- Classification accuracy 0.025mm (400 mesh), overflow fineness -0.074mm containing ≤10%
- Concentration ratio up to 1:15 (traditional equipment 1:8)
✅ Super wear resistance
- Lined with silicon carbide ceramic (Mohs hardness 9.2) or polyurethane (Shore hardness 95A)
- Continuous operation life ≥50,000 hours
✅ Intelligent regulation
- Automatic pressure monitoring (0.05-0.35MPa adjustable)
- IoT remote warning of blockage risk
✅ Multi-scenario adaptation
- Metal ore version: wear-resistant ceramic lining (gold/iron ore slurry classification)
- Chemical version: 316L stainless steel/PP material (acid and alkali corrosion resistant)
- Sand and gravel version: anti-blocking feeder (high sand content working condition)
