Wedge Wire Screen Cylinder
- Screen Cylinder — Axial Internal Wire
Screen Cylinder — Axial Internal Wire
This type of filter tube is characterized by an axial profile wire/axial slot direction. The support wire is oriented on the outside of the filter element in a radial direction. The smooth surface of the profile wire is on the inside and the filtration direction is therefore from the inside to outside.

Slot tube for Self Cleaning Filter
A kind of slot tube where the slot runs in the axial direction, with smooth surface on the inside can be cleaned by a suction plate, a scraper or by Bernoulli effect.
Pressure Screen for Pulp&Paper
The design of wedge wire screen fiber basket, produces a continuous slot over the length of the basket. Vertical parallel rods, or wires, are arranged in a circle to form a cylindrical shape. The wires are held mechanically in place with metal bands or rings. The size of the gap, or slot, between the wires is precisely set — typical values are 0.10 mm, 0.15 mm, and 0.20 mm.

Starch Screen
The Wedge Wire Starch Curved Screen is a curved screening device specifically designed for the starch industry. It features an arc-shaped screen surface made of precisely welded V-profile stainless steel wires, utilizing centrifugal force or gravity to achieve rapid dewatering and classification of starch slurry. Its curved structure prolongs slurry retention time, improving solid-liquid separation efficiency. It is suitable for starch extraction, refining, and byproduct recovery processes for starches such as potato, corn, and cassava. Characterized by efficient screening, wear and clogging resistance, and easy maintenance, this equipment is a key solid-liquid separation device in modern starch processing.
Rotary Drum
The Stainless Steel Wedge Wire Rotary Drum Screen (also known as a Rotary Drum Strainer or Micro-Screen) is a continuously and automatically operating front-end solid-liquid separation device. Its core component is a large cylindrical drum installed horizontally or at a slight incline. The entire circumferential surface of the drum is covered with a stainless steel wedge wire screen (Johnson screen). The wastewater to be treated flows into one end of the drum. Under gravity, the filtrate passes through the wedge wire slots, while solid suspended matter (such as fibers, hair, plastic pieces, and fine particles) is retained on the inner surface of the drum. As the drum rotates slowly, the retained debris is lifted to the top, where it is flushed by spray water into a collection trough, achieving a continuous process of automatic screening, filtration, and residue removal
Screen Basket for Screw Press Separator
The stainless steel wedge wire screen basket, commonly known as the "V-wire screen," "press screen basket," or "screen cylinder," is a core component of screw press solid-liquid separators. It is installed inside the spiral press, enclosing the rotating screw shaft. The working principle is as follows: raw slurry with high moisture content is pushed into the screen basket by the screw shaft. Under the squeezing and conveying action of the spiral flights, the liquid (filtrate) is forced out through the precise, continuous slots of the screen basket, while the solid material (manure cake) is retained inside and continues to be compressed and dewatered as it moves forward. Finally, the dewatered solids are discharged from the outlet, achieving solid-liquid separation.
Wedge Wire Vibrating Screen
A stainless steel wedge wire vibrating screen is a solid-liquid separation device featuring a screen surface made by precisely welding V-shaped stainless steel wires, integrated with a high-frequency vibration system. With uniform slots, wear resistance, and corrosion resistance, it is suitable for wet screening and dewatering operations. The vibration mechanism enables rapid material dispersion and efficient sieving while effectively preventing screen clogging. Widely used in industries such as mining, metallurgy, food processing, and environmental protection, it is particularly suitable for handling fine particles, high-viscosity, or easily agglomerated materials, offering advantages such as high screening accuracy, large processing capacity, and long service life.
Wedge Wire Water Well Screen
Johnson Deep Water Well Screens, also referred to as continuous slot screens or wire wrap screens, were originally developed to solve sand control challenges in fine-grained and uniform sand formations. These geological conditions are commonly encountered in deep groundwater aquifers, where conventional perforated pipes often suffer from clogging, excessive sand production, and reduced well efficiency.
Sintered Mesh Plate and Disc
Sintered Mesh Plates and Discs are high-precision filtration components fabricated by bonding multiple layers of stainless steel wire mesh through a specialized vacuum sintering process. Unlike traditional mesh that relies on mechanical weaving alone, these plates are fused at every contact point, transforming individual wires into a rigid, integrated porous metal sheet.
These plates can be customized into various shapes, most commonly circular discs, to fit specific industrial equipment. They offer an ideal balance of high permeability, extreme structural integrity, and precise filtration ratings. Because they are made entirely of metal (typically 304 or 316L), they provide a "permanent" filtration solution that can withstand high temperatures and corrosive chemicals while remaining fully cleanable and reusable.
