What are screen panels made of?

Polyurethane Screen Panel used in a variety of industries including mining, aggregate processing and waste management are often made from a variety of materials, depending on the specific application and requirements.

Material selection is influenced by a variety of factors, such as the type of material being processed, particle size, the wear resistance of the material, and the required durability of the screen deck.

Here are some materials commonly used for screen panels:

  1. Woven Wire Mesh:

This is one of the most traditional materials used for screen panels. It consists of metal wires woven together to form a mesh. The material of the wire can vary and can include stainless steel, high carbon steel or other alloys. Mesh size can also be varied to accommodate different particle sizes.

  1. Polyurethane:

Polyurethane screen panels are known for their durability and resistance to wear and tear. They are particularly suitable for screening applications where the materials being processed are abrasive. Polyurethane panels are also flexible and can be manufactured into a variety of opening sizes and shapes.

  1. Rubber:

Rubber screens are used in applications requiring impact resistance and noise reduction. They are commonly used in mineral processing and aggregate screening. The rubber material helps absorb the impact of larger particles on the screen.

  1. Perforated Plate:

Instead of woven mesh, screen panels can be made from perforated plates. These plates have holes of various shapes and sizes punched through them. The choice of material for perforated plates can include stainless steel, mild steel, or other metals.

  1. Modular Panels:

Modular screen panels are often made of polyurethane or rubber and are designed to be easily interchangeable. These panels can be snapped or bolted into place on a screen deck, allowing for quick and convenient replacement.

Screen panels come in various types, each designed for specific applications and materials. The choice of screen panel depends on factors such as the type of material being processed, particle size, and the desired screening efficiency.

Here are some common types of screen panels:

  1. Woven Wire Mesh Panels:

Description:

Woven wire mesh is a traditional and widely used type of screen panel. It consists of interwoven metal wires, creating a mesh with openings of various sizes.

Applications:

Suitable for a wide range of materials and industries, including aggregate processing, mining, and mineral processing.

  1. Polyurethane Panels:

Description:

Polyurethane screen panels are made from Polyurethane Screen Panel material, which offers excellent wear resistance and durability. These panels can be molded with various opening shapes and sizes.

Applications:

Commonly used in industries where abrasion resistance and flexibility are crucial, such as aggregate screening and mining.

  1. Rubber Panels:

Description:

Rubber screen panels are designed to absorb impact and vibration, offering good wear resistance and noise reduction.

Applications:

Suitable for applications where noise reduction and impact resistance are important, such as in mineral processing and quarrying.

  1. Perforated Plate Panels:

Description:

Perforated plate panels are made from metal plates with holes of specific shapes and sizes punched through them.

Applications:

Used in various industries, including agriculture, food processing, and water treatment, depending on the perforation pattern.

  1. Modular Panels:

Description:

Modular screen panels are typically made from rubber or polyurethane and are designed to be easily interchangeable. They often have a snap-in or bolt-down system.

Applications:

Widely used in applications where quick and convenient panel replacement is desired, such as in aggregate processing and modular screening systems.

  1. Wire Cloth Panels:

Description:

Similar to woven wire mesh, wire cloth panels are made by weaving metal wires to form a fabric-like material.

Applications:

Used in various industries for particle separation based on size, including agriculture and food processing.

  1. Punch Plate Panels:

 

Description: Punch plate panels consist of a metal plate with punched holes that are typically larger in diameter than those in woven wire mesh.

Applications: Suitable for applications where large particles need to be separated, such as in the mining and construction industries

  1. Wire Cloth:

Similar to woven wire mesh, wire cloth is a fabric-like material made by weaving metal wires. It is commonly used in applications where a finer mesh is required for more precise screening.
