Alumina ceramics (Al2O3≧95%,life extended by 50%)

Shell: Carbon steel Q235B (sandblasting anti-corrosion) or 304 stainless steel (resistant to Cl corrosion)

Key components: Sand settling nozzle: quick-detachable silicon carbide (Si) nozzle (diameter 15-40mm optional)

Overflow pipe: adjustable height design (±20mm fine-tuning classification accuracy)

Feed distributor: hydraulic balance design (to ensure uniform pressure of 14 units)

3.Performance parameters

Working pressure: 0.1-0.3MPa (recommended 0.15-0.2MPa)

Separation efficiency: Underflow yield: 30-50% (related to the particle size distribution of the feed)

Overflow fineness (200 mesh proportion): 70-95%

Pressure resistance grade: ≤0.6MPa (burst pressure test value)

4.Power and supporting

pump requirements:

Flow rate: 400-800m³/h (lift 20-30m)

Power: 90-160kW (frequency conversion control is preferred)

 Pipeline interface:

Feed pipe: DN200 flange (GB/T 9119)

Overflow/underflow pipe: DN150 flange (wear-resistant hose is optional)

5. Equipment size and weight

 Single unit size: φ250mm×1600mm

Total weight including distributor: 2.54 tons (depending on the material)

6. Intelligent control (optional)

Automation solution:

Pressure sensor + PLC dynamically adjusts the diameter of the sand settling nozzle

Online particle size analyzer (real-time feedback d50 and automatic optimization)

Wear-resistant monitoring: Lining wireless thickness sensor (early warning replacement)

7.Typical application scenarios

Metal ore classification:

Desludging before copper/molybdenum ore concentration d50=20μm)

Particle size control before iron ore reverse flotation (d50=45μm)

Non-metallic minerals: Key points for hydraulic classification of 30μm ultrafine powder

Kaolin by quartz sand removal

Ключевые моменты

1.Process adaptability:

High viscosity slurry (such as lithium mica) needs to reduce the processing volume by 10-15% When it contains long fiber impurities, a pre- screen (such as 3mm grid) is required

2. Maintenance points: Check the wear of the sand settling nozzle every shift (replace it when the diameter increases by 10%) Clean the feed distributor monthly to prevent clogging

If need full ceramic lining and super wear-resistant models or GIS intelligent distribution system (pressure fluctuation ≤2%) Selection suggestions

If used for gold cyanide pre-leaching classification (requires d50=30μm):

Choose PU lining + 35mm sand settling nozzle

matching pump pressure is stable to 0.18MPa

If  need more specific slurry viscosity flow correction factor table or material acid and alkali resistance data, please provide mineral composition (such as sulfur, fluorine, etc.).
