Heavy-Duty Johnson Screen Baskets for Advanced Industrial Separation
Our Wedge Wire Baskets are engineered for superior screening and dewatering in high-demand environments. Constructed with trapezoidal-section "V" wires fusion-welded to internal support rods, these baskets offer a precise, continuous slot structure that maximizes flow and eliminates clogging.
· Custom Precision: Slot openings from 0.1 mm to 45 mm with micro-level accuracy.
· Structural Integrity: Robust SS304/316L base withstands differential pressure up to 6Kg/cm².
· Non-Clogging Design: Self-cleaning V-shape allows particles to slide off easily, ensuring stable flow.
· Versatile Shapes: Available in cylindrical, conical, and rectangular configurations.
· Supply Reliability: 1,200 tons/month production capacity for rapid global fulfillment.
The Stainless Steel Wedge Wire Screen Basket (Johnson screen basket) is a high-performance filter insert designed for solid-liquid or gas-solid separation. By fusion-welding triangular-section profile wires onto support rods, we create a rigid, rugged structure that provides a smooth surface and high mechanical strength.
Designed for precision filtration (ranging from 15μm to 800μm), these baskets are essential in harsh working conditions. Unlike traditional mesh, the wedge-shaped slots widen inwardly, allowing particles that pass the initial opening to move freely, which facilitates efficient back-washing and maintains long-term operational efficiency.

Key Advantages
Superior Anti-Clogging: The V-profile prevents impurity entrapment, making it the ideal solution for filtering slurries and juices.
Enhanced Durability: Fusion-welded construction resists impact and deformation even in mining and metallurgy applications.
High Effective Open Area: Controllable back-width of the wire determines the aperture ratio, maximizing free flow and reducing pressure drop.
Easy Maintenance: disassemblable without risk of damage to the filter surface, facilitating long-term service life.
Industrial Applications
Beer and Beverage: High-precision wedge wire filters ensure the clarity and purity of beer, wine, and syrups by providing efficient diatomaceous earth filtration and yeast removal.
Grain and Food Processing: Versatile screening solutions for sifting, drying, and grading grains, starch, and flour while meeting strict food-grade hygiene standards.

FAQ
Q: Why are wedge wire baskets preferred for starch and beverage filtration?
A: The smooth surface and non-clogging V-wire geometry provide a high effective open area, which maximizes throughput and reduces pressure drops in high-viscosity liquids like starch slurry or fruit juice.
Q: Can these baskets be used in centrifuges for dewatering?
A: Yes, our baskets are engineered with heavy-duty support rods (up to 5.0mm) to handle the high centrifugal forces and abrasive wear typical of mining and food dewatering centrifuges.
Q: Are the baskets easy to maintain and clean?
A: Yes, the V-shape slots facilitate efficient back-washing. Furthermore, our baskets can be supplied with polished or passivated finishes to meet strict pharmaceutical and food-grade hygiene standards.
Q: Do you produce conical-shaped wedge wire baskets?
A: Yes, we provide full customization for the basket shape, including cylindrical, conical, and rectangular configurations, to meet the specific requirements of your separation equipment.
