Polyurethane Hydrocyclone Spigot / Apex Nozzle

Core Advantages

1. Superior Wear Resistance for Extended Service Life

• Excellent Wear Resistance: The abrasion resistance of polyurethane material is extremely outstanding, 3-5 times that of ordinary rubber and 2-4 times that of high-chromium cast iron. Under high-speed scouring by hard particles such as quartz sand and metal ore particles, its wear rate is extremely low, with a service life of 8,000 to 12,000 hours, more than 3 times that of traditional metal hydrocyclone nozzles.

• Excellent Impact Resistance: Possessing high modulus of elasticity and elongation at break, it effectively absorbs impact energy from high-speed slurry discharge without brittle fracture or cracking, perfectly adapting to harsh mining working conditions.

2. Fluid Dynamics Optimization for Efficient Anti-Blocking

• Streamlined Inner Wall Design: The discharge end typically features a gradually converging bell-mouth design (with precisely calculated contraction angle), and the inner wall is extremely smooth with no dead corners. This design minimizes fluid resistance, prevents sediment deposition and blockage, ensuring smooth sand discharge.

• Improved Separation Efficiency: The optimized internal flow path effectively controls slurry concentration and flow velocity, achieving a solid particle separation rate of over 95%. In fine sand recovery or gravity separation processes, it significantly improves the recovery rate of heavy minerals or fine sand.

3. Corrosion and Weather Resistance with Strong Adaptability

• Excellent Chemical Stability: Possesses extremely strong resistance to acids, alkalis, salts, and various corrosive media in slurry (pH 4-12). Under harsh conditions containing chlorides or sulfides, its corrosion-resistant service life far exceeds that of stainless steel.

• Wide Temperature Range Operation: Maintains excellent flexibility and physical properties over a wide temperature range of -30℃ to 80℃, without becoming brittle at low temperatures or aging at high temperatures, ensuring all-weather stable operation of the equipment.

4. Lightweight Design and Convenient Maintenance

• Reduced Equipment Load: With a density only about 1/7 that of steel, it is extremely lightweight, significantly reducing the overall weight of the cyclone assembly, and is very easy to install.

• Excellent Sealing: Fits tightly with the cyclone cone or pipeline, and with flanges or clamps enables quick disassembly and assembly, effectively preventing slurry leakage and avoiding resource waste and environmental pollution.

Technical Parameters

• Material: High-performance wear-resistant polyurethane elastomer (polyester or hydrolysis-resistant polyether type available depending on operating conditions; ceramic particle reinforcement can be lined upon request)

• Hardness Range: Shore 85A – 95A (balancing extreme wear resistance and impact resistance requirements)

• Diameter Range: DN25 – DN200 (non-standard customization per drawings and specific cyclone models supported)

• Temperature Range: -30℃ to 80℃ (normal operating conditions; special formulations can withstand higher temperatures)

• Applicable Pressure: 0.1 – 2.5 MPa (wall thickness and structure can be customized according to actual feed pressure)

Application Areas

Widely used in mining beneficiation (classification and concentration of iron ore, copper ore, gold ore, etc.), coal washing (coal slurry separation), sand and gravel aggregate plants (fine sand recovery and dewatering), tailings filling and dam construction, as well as slurry purification and solid-liquid separation operations in chemical and environmental protection industries. Compatible with various FX series hydrocyclones and fine sand recovery units.
