Wedge Wire Screens can be employed for Employed for fine material screening, dehydration, and de-sludging in equipment like vibrating screens, gravity screens, and mineral processing screens. Applications include sewage treatment, pharmaceutical filtration, and food/beverage industries.
Widely used in sludge dewatering machines, printing and dyeing sludge filtration, starch screening, beer fermentation tanks, and solid-liquid separation systems. Also integral to oil extraction devices and automatic cleaning filters.
Applied in petrochemical reactors, coal washing plants, metallurgy, and environmental protection systems for filtration, separation, and media retention.
Specifications:
Filtration Precision: Ranges from 0.02 mm to 10 mm (20 μm to 10,000 μm), adjustable based on application needs.
Material Composition: Primarily stainless steel grades 304 and 316L; other options include carbon steel, titanium, Hastelloy, and epoxy-coated steels for enhanced corrosion resistance.
Structural Design: Features V-shaped wires welded onto support rods, creating trapezoidal slots with a wider top and narrower bottom to resist clogging. Configurations include flat panels, curved baskets, or cylindrical forms.
Dimensions: Customizable; typical diameters range from φ19 mm to φ900 mm, lengths from 23 mm to 3000 mm, and slot depths determined by wire height.
Slot Characteristics: Gap widths are uniform and directional, supporting high open area percentages for efficient fluid flow and self-cleaning.
