Vibrating Screens
- Wide range of screen section specifications
- Available in stainless steel and other specialty metals
We supply a wide range of screen section specifications in square mesh or oblong weaves. Each screen section is provided with the proper edge preparation to suit the wire cloth selected and to fit the screening machine on which it will be used.
Vibrating screen sections are available in stainless steel and other specialty metals. Cloth for popular specifications and standard hooks are stock items. Complete screens in standard sizes, such as 4'x5', 4'x8', and 4'x10' are also readily available.
Edge Preparation
Our vibrating screens’ standard hook design is the square two-piece hook with insert. This hook is particularly effective for lighter wire screens, as the rubber strips on both sides of the cloth prevent metal-to-metal contact and the resulting wear and screen failure.
For heavier screens or special applications, various other hooks are available. All hooks are available in galvanized steel, stainless steel or copper for heated screens
For Longer Screen Life
Back-up Screens – Some vibrating screen users find that screen life is increased by using a back-up screen. The coarser mesh wire cloth supports the load while the fine mesh actually performs the screening.
A back-up is normally used with screens of 80 mesh and finer. Various meshes are used, such as 12, 20, or 30 mesh, depending on the specific application.
Tensioning – Proper tensioning of a vibrating screen is an important factor in screen life. Tension should be distributed evenly along the length of the hooks, and screens should be re-tensioned periodically to maintain optimum capacity and screen life.
Half-Panels – Since the greatest wear occurs where the load impacts the screen, this area often fails first, requiring replacement of the entire section. An alternative for 8' and 10' long screens is to use two half-panels joined by a 1? extension of cloth to make up the length. This may require modification of the screen box, but can result in significant savings on replacement screens (the half-panels can be reversed to distribute the wear, and can be replaced one at a time).
Screening Capacity – Effective screening area, screening rate and screen section life have a significant relationship to each other. Generally, in any given size opening, larger wire sizes provide longer life, but less screened material. Conversely, smaller diameter wires give greater capacity, but shorter service life. The illustrations above demonstrate the relationship between mesh, wire size, open area and screening capacity.
