FAQ

  • Q How do polyurethane screens outperform metal alternatives in mining operations?​

    A
    Our polyurethane screens deliver:
    ​​200% Longer Lifespan​​: Resistant to abrasion from ore impact (ASTM D4060 test: ≤38mm³ loss)
    ​​Zero Corrosion​​: Immune to pH 2-14 chemical environments vs. metal screen oxidation
    ​​Noise Reduction​​: 15dB lower operational noise.
  • Q What materials are commonly used for wedge wire manufacturing?

    A Wedge Screen is mainly made of stainless steel (304/316L), Hazelloy, titanium alloy and polypropylene (PP/PVDF) and other materials, its all-welded structure ensures high stability, V-shaped wedge wire design combined with material characteristics, to achieve anti-blockage, self-cleaning and health safety. Meet the diversified needs of industrial filtration for temperature resistance (-200℃ to 550℃), pressure resistance (above 30MPa) and precision separation. 
  • Q Can polyurethane screens handle high-temperature ores?​

    A

     Yes, with critical thresholds:
    1.Temperature Range:-40°C to 80°C.  Performance Status:Optimal screening efficiency
    2.
    Temperature Range:80°C to 110°C.    Performance Status:Requires HS-90 compound
    3.Temperature Range:>110°C.              Performance Status:Not recommended

  • Q What is a wedge wire screen?

    A The Wedge wire Screen is a precision filtration device based on the V-shaped wedge wire wound and support rod welded structure for efficient solid-liquid/gas separation. The design of the V-shaped structure is narrow outside and wide inside to reduce the particle stuck, and has the characteristics of anti-clogging and self-cleaning (impurities are easy to fall off when backwashing). Widely used in petrochemical, water treatment, food medicine and other fields, is a variety of filter components.
  • Q How long has your company been established?

    A Established in 2016,SLOT is dedicated to manufacturing wedge wire screens.we provide customers with comprehensive, one-stop filtration solutions.
  • Q What international certifications have your products passed?

    A SLOT has obtained ISO9001 quality management system certification and achieved certification from SGS ,demonstrating our commitment to quality management.
  • Q How do you guarantee the quality of your products?

    A Through the whole process quality control system + strict testing standards + customer co-creation verification triple guarantee, to ensure that every product meets or exceeds the industry performance requirements.
  • Q What are the core advantages of polyurethane screens?​

    A

    ​​​Extended Lifespan​​: Average 22 months (vs. 4-8 months for metal screens).
    ​​Zero Maintenance​​: No rust prevention/lubrication required.
    ​​Noise Reduction​​: ≤75 dB (OSHA compliant).​​
    Corrosion Resistance​​: Withstands pH 1–14 environments.
