Slotted wedge wire screens
Tailor-made solutions for demanding screening and separation processes in a variety of industrial areas
ANDRITZ Euroslot and ANDRITZ Fiedler, both members of the ANDRITZ GROUP, together provide a unique breadth and depth of expertise across a range of industry sectors – from oil and gas, to petrochemicals and refineries, water treatment, filtration, food processing, and the paper industry.
Slotted wedge wire screens are the answer to the most challenging screening and separation processes, where high throughput, precision, and screening efficiency are the parameters that matter.
Optimized processes in the feed and food industries
ANDRITZ wedge wire screens offer excellent possibilities for optimizing separation and filtration processes. Thus, wedge wire screens with their continuous slots have substantially more open area and very precise openings compared to wire meshes or perforated material. The stable and durable design extends the life cycle, and the slots are low-maintenance and almost free of plugging due to the shape of the profile wires. With the development of our filter elements, we always have the reliability and productivity of your application in mind. Wedge wire screens offer exceptional design variety. This facilitates a large range of types and sizes, as well as variable possibilities for use in sensitive areas of food and animal feed production thanks to the use of high-quality materials and improvements.
The following list provides examples of some products and applications:
- Fine slot candle filters
- Centrifuge inserts
- Lauter vats/brewers’ floors
- Inclined grids for starch mills
- Floors with nozzles
Increasingly efficient processes for water treatment
Water is a precious resource. When it comes to successful water treatment, the most important factors are low maintenance cost, large open area, easy cleaning, a long service life, and process reliability. Wedge wire screen technology from ANDRITZ offers a variety of application possibilities here. These are, for instance, water intake for obtaining cooling water, process water or domestic water, water filtration, and retention of solids such as active carbon or resins. The design of the screens is optimized to ensure the most uniform possible flow and to prevent screen clogging. Here are some examples of ANDRITZ wedge wire screen components used in the water treatment sector:
- Water intake systems
- Resin traps
- Bow screens
- Distributor/collector systems
- Support screens
- Strainer cartridges
More efficient stock preparation with lower maintenance costs
In many industrial processes, dewatering, grinding or separation of materials is an essential parameter that influences both the quality of the end product as well as the energy requirement. In most cases, separators, presses, mills, or centrifuges are used for dewatering. ANDRITZ has decades of experience in solid/liquid separation and supports you in the selection and design of the optimum screen components for your process. The emphasis is on high-quality products with a long service life and high level of screen resistance. Use of corrosion-resistant steel reduces the maintenance costs and thus increases the productivity of machines and systems. Here are some examples of ANDRITZ wedge wire equipment used in stock preparation:
- Rotation screens/rotary drums
- Mill screens
- Screw presses and separators
Precise separation processes for the chemical industry
In the manufacture of chemical products, wedge wire screens are used predominantly for separation purposes. Supporting grids, collectors/distributors, nozzle plates, and radial flow components are designed and produced by ANDRITZ Fiedler. Wedge wire screens ensure precise separation and long operating times due to the large open area and high surface quality. The wide range of materials available allows the designs to be adapted to the respective process requirements with the aim of extending running times and keeping the maintenance costs as low as possible. With its vast experience, ANDRITZ Fiedler offers reliability and high quality. Here are some examples of ANDRITZ Fiedler wedge wire screen components that are used in the chemical industry:
- Radial flow components
- Nozzle floors
- Supporting grids
- Distributor/collector systems
Solid/liquid separation in biomass separators
In screw type separators, viscous media are pressed to increase the solids content to up to 35%. In these processes, the general rule is that the higher the solids content, the more efficient and less energy-intensive the downstream process step.
The optimized ANDRITZ wedge wire screen baskets for screw separators have a large open screen surface, are less prone to clogging, and offer very good accuracy of form and fit. This makes the entire separation process more reliable, requiring less maintenance and enhancing energy efficiency.
Regardless of the equipment you are using, a wedge wire basket from ANDRITZ combined with our service will allow you to improve dewatering and/or separation and thus enhance the quality and shelf life of your end product. It can even have a decisive impact on the energy requirement of your entire facility.
ANDRITZ has extensive experience in solid/ liquid separation and can assist you in selecting and designing the best screen components for your process with a focus on high-quality products, a long service life, and screens that are highly durable.
