The industrial screens are made by welding the v-shaped wires into various shapes and sizes of support rods. The process used for producing an industrial screen creates a slit that enlarges inwardly and creates a large clog-resistant surface and open area. A quality industrial screen is one that has outstanding durability, ruggedness, consistency, slot opening, and resistance to abrasion.
The screens are majorly used for two reasons in the industries:
- Direct screening
- Filter media support (resins, sand bed, activated carbon, catalysts)
The industrial screens are available in different slot openings ranging from 25 μm to 0.984 in. (that is 25 mm). The most commonly used materials are stainless steel (the 300 series), also other exotic alloys are used that are available to satisfy specific applications.
The industrial screen is available in different shapes such as cones, cylinders, curved or flat panels, and there’s also an option to produce it in any form specific to a particular application. The versatility offered by the process allows the manufacturing of custom screens for various applications such as upgrades, expansions, or new plants.
The industrial screens achieve maximum effectiveness and efficiency in processes that involve any aspect of solid/liquid/fluid separation. The precision, strength, and design flexibility of industrial screens make them a choice in various industries across the globe. To name a few of the industries:
- Pulp and paper
- Water and wastewater
- Chemical Architectural
- Mineral and aggregate processing
- Water supply
- Machine coolant filtration
- Plastics extrusion
The typical application of industrial screens include:
- Media retention
- Fish diversion
- Water intake
For the industrial screen, standard welding construction is used that uses resistance-welding. It is carried out in a continuous elliptical motion to further join it with rods and wires. As it circulates, the resistance weld runs the uninterrupted length of wire to the rod. These screens are made in various formations such as flat, cylindrical, or curved. Any variation in rod and wire sizes and the slot opening can be chosen to produce the according to your expectation (that is customized type).
Now, considering looped wire construction, such industrial screens have a variety of applications as well. This type of construction eliminates the requirement of welding to join the wire and the rod. Also, it majorly increases the durability of the screen in most applications. This type of construction also adds great flexibility to the industrial screens and allows to produce different openings, profile shapes, short-member configuration, etc.
The manufacturing and design characteristics of industrial screens give the following benefits:
- Non-clogging surface
- Mechanical strength
- Large open area
- Hydraulic efficiency
- Low-pressure drop
- Easy cleaning
- High flow rates
The industrial screens are sturdy and compact which enables easy adaptation of an area. Due to its versatility of rod and wire shapes, it has possibly achieved an optimum open area, the balance of strength, dewatering and separation efficiency, and abrasion resistance. The material used to make the industrial screens are stainless steel in different alloys, mild steel wire, spring steel (high carbon steel), copper, brass, galvanized iron, etc.
