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:
- 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.
- 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.
- 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.
- 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.
- 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.
