Sieve Bend Screen

Sieve Bend Screen

Sieve bend screen is a type of curved wire mesh screen used for solid-liquid separation in various industrial applications. It is specifically designed to handle high volumes of water with fine particles or solids and provide effective dewatering and solid separation.

Sieve bend screen features a curved or arc-shaped surface that allows for efficient particle separation and dewatering. The curved design creates a gentle slope, promoting the self-cleaning action and preventing clogging. The screen is typically made of stainless steel or other corrosion-resistant materials to withstand harsh operating conditions.


The main purpose of a sieve bend screen is to separate solids from liquids, allowing the liquid to pass through while retaining the solid particles on the screen’s surface. Separation is achieved through the use of precise slot openings on the curved surface of the screen. The slot openings can be customized to suit specific application requirements, allowing for efficient particle size separation.

The advantages of sieve bend screens include their ability to handle high volumes of water, their self-cleaning action, and their durability in demanding environments. Curved surface design minimizes clogging and maintenance requirements, allowing for continuous operation. The precise slot openings enable effective particle separation and efficient dewatering. Additionally, sieve bend screens can be customized to meet specific application requirements, including slot size, screen width, and curvature

8.Packaging and delivery: Package the sieve bend screens securely for transportation to the customer’s location.

Material of sieve bend screen

Material of sieve bend screen

Sieve bend screens are typically made from high-quality materials that offer durability, corrosion resistance, and compatibility with the application requirements. The most common material used for sieve bend screens is stainless steel, particularly grades such as 304 or 316 stainless steel.

Stainless steel provides excellent resistance to corrosion, high temperatures, and abrasive environments, making it suitable for a wide range of industrial applications. Other materials, such as mild steel or polyurethane, can also be used depending on the specific needs of the application. The material selection is crucial to ensure longevity and performance in solid-liquid separation processes.

Construction of sieve bend screen

Construction of sieve bend screen

The construction of a sieve bend screen typically involves a combination of wire mesh and a supporting frame. The wire mesh is formed into a curved or arc-shaped configuration, allowing for effective solid-liquid separation. It is typically made from stainless steel or other corrosion-resistant materials. The curved wire mesh is then attached to a sturdy frame, which provides support and stability.

Frame is often made from metal, such as steel or aluminum, and can be reinforced as needed. The construction ensures that the sieve bend screen can withstand the operating conditions and effectively separate solids from liquids with minimal clogging.

sieve bend screen working principle

sieve bend screen working principle

The working principle of a sieve bend screen is based on the curved design and precise slot openings. When a slurry or liquid-solid mixture is fed onto the curved surface of the screen, the liquid passes through the slots due to its smaller particle size.

At the same time, the larger solid particles are retained on the surface of the screen. The curved shape of the screen promotes the self-cleaning action, allowing the solids to slide down and preventing clogging. This separation process effectively separates the solid particles from the liquid, allowing for dewatering and solid-liquid separation in various industrial applications.


Most frequent questions and answers

Static sieve bend screen filters are a type of filtration equipment used for solid-liquid separation. They consist of a curved wire mesh screen with precise slot openings that retain solid particles while allowing liquid to pass through. The term “static” refers to the fixed position of the sieve bend screen, which means it does not have any mechanical or moving parts during operation.


Static sieve bend screen filters are commonly used in applications where continuous, non-mechanical filtration is required, such as in wastewater treatment, mining, food processing, and chemical industries. They offer efficient particle separation and require minimal maintenance.

Curved wedge wire screen design contributes to its effectiveness in solid-liquid separation in several ways.


First, the curved shape allows for a larger effective filtration area compared to a flat screen, maximizing the contact between the screen and the liquid-solid mixture. This increased surface area enhances the filtration capacity and efficiency.


Second, the curved surface promotes the self-cleaning action by facilitating the movement of solids down the screen. This helps prevent clogging and maintains a continuous flow of liquid through the screen.


Finally, the precise slot openings on the curved surface enable the separation of solid particles based on their size, allowing the liquid to pass through while retaining the solids on the screen. This ensures efficient separation and high-quality filtration.

When selecting sieve bend screen filters for a specific application, consider factors such as the desired separation efficiency, particle size distribution, flow rate requirements, chemical compatibility with the process fluids, operating temperature and pressure conditions, maintenance and cleaning requirements, and the overall durability and lifespan of the screen.


Additionally, evaluate the reputation and experience of the manufacturer, customization options available, and any industry-specific standards or regulations that need to be followed. By considering these factors, you can choose a sieve bend screen that is well-suited to your specific application and ensures optimal performance.

Appropriate slot size or opening size for a sieve bend filter screen is determined by considering the particle size distribution of the solid particles to be separated. The goal is to select a slot size that allows the desired range of particle sizes to pass through while retaining larger particles. This can be achieved through particle size analysis or referring to industry standards and guidelines.


Additionally, considering the desired separation efficiency, flow rate, and the characteristics of the process fluid can help in determining the appropriate slot size for optimal filtration performance.

Sieve bend screen and demister filter are both types of industrial filtration equipment but serve different purposes.


Sieve bend screen is used for solid-liquid separation, where the curved screen allows liquid to pass through while retaining solid particles. It is commonly used in applications such as dewatering, solid separation, and particle size classification.


On the other hand, demister filter is used for gas-liquid separation. It removes entrained liquid droplets from gas streams by coalescing them into larger droplets that can be separated and drained.


While both technologies involve separation processes, they are designed for different phases (liquid-solid vs. gas-liquid) and have distinct mechanisms and applications.

Flow rates that stainless steel sieve bend screens can handle depend on various factors, including the screen size, slot openings, and the characteristics of the liquid-solid mixture. Generally, sieve bend screens can handle flow rates ranging from a few hundred liters per hour to several thousand liters per hour.


However, for larger industrial applications, the flow rates can go up to tens of thousands or even hundreds of thousands of liters per hour. It is important to consult with the manufacturer or supplier of the sieve bend screen to determine the specific flow rate capabilities for a given screen size and slot opening configuration.

To ensure optimal performance of a DSM sieve bend screen, regular maintenance and cleaning procedures are recommended. Here are some common practices:


1.Regular inspection: Inspect the screen for any signs of damage, wear, or clogging. Replace or repair any damaged or worn components.


2.Cleaning: Clean the screen periodically to remove accumulated solids or debris. This can be done using water, brushes, or gentle air pressure to dislodge the particles.


3.Backwashing: Backwash the screen with clean water or an appropriate cleaning solution to remove any stubborn or trapped solids.


4.Lubrication: Apply lubrication to moving parts, such as pivots or bearings, as recommended by the manufacturer.


5.Record keeping: Maintain records of maintenance activities, inspections, and any performance issues for future reference.
