01. If it breaks at the feed end of the deck:

· Make sure to spread the material feed evenly to the full width of the screen bed in order to use the complete screening surface of the deck.

· Reduce feed height to avoid high impact on the screening media.

· Use the correct screening media, you may want to use at the feed end perforated plates, rubber or polyurethane that have a higher resistance to high impact and abrasion.

02. If it breaks along the support bars:

· Check that the and re-check this at regular intervals. This is the main cause of premature screen failure. If the screen is loose it will be vibrating and banging the support bars, creating micro fractures along the support bar that will result in screen damage. Also make sure to allow enough space (H) on both sides of the screen to tighten it symmetrically, the hook of the screen should never touch the machine’s side.

Check the correct position of the side plates one side plate on one screen, so that there is an even tension on the screen. If one side plate is tensing two screens, the screens will never be tensed correctly.

Check you use rubber liners on the deck’s support bars and that they are in good condition. When the rubber liner is worn or broken it will create gaps between the mesh and the deck, creating soft and weak areas on the mesh.

If you are using self-cleaning screens make sure the polyurethane bands coincide with the deck’s support bars, if they don’t it will generate potential blind areas and loose screening surfaces.
