Screen Installation

Custom manufactured in five basic styles, these screens greatly reduce pegging, plugging and blinding while still separating flakes and slivers from finished product.

All types have extremely high percentages of open area when compared to square opening woven mesh, thus giving higher production rates.

All products are available in Oil Tempered and Stainless Steel wire and can be hooked with any edge style to fit all screening equipment, stationary or portable.

1. Channel rubber or crown bar rubber must be replaced before new screens are installed to assure longer screen life.

2. Use new tension bolts and tension all bolts equally on both sides of the vibrator.

3. Screens should be centered on the deck before clamping rails are applied.

4. Make certain butted screen panels are tight together to avoid oversized material leakage.

5. Clamping rails must be exact length of the screen panel being installed. Never overlap clamping rails.

6. After 4 to 8 hours of operation, retighten the screen to take up any stretch that might occur.

Screen Maintenance

1. Inspect all clamping bars for corrosion and wear.

- Make sure bars are not warped or worn to the point that they cannot provide even, tight tension.

2. Inspect all nuts and bolts.

- Replace all worn or stripped parts in the screen assembly.

- All hole positions on clamping bars must be used.

3. Maintain support deck.

- Remove channel rubber to inspect steel bars for wear, high and low spots or bar breakage.

- Support area must be uniform to ensure even and tight fit.

4. Change your channel rubber frequently.

- Twin City Wire recommends changing channel rubber every time the screen is replaced, or at least every other time.

- Remember that channel rubber will wear from the bottom up as well as from top down. Check both sides.

- Never mix channel rubber sizes or styles such as Flat-Top and Round-Top on the same deck.

5. Check cushion and spread of material feed.

- Cushioning of feed to the screen deck is essential to long screen life. Use feed plates or stone boxes so that materials do not hit wire cloth directly.

- Material should be spread out to feed evenly over the entire screening surface for maximum screen life and production. This also reduces uneven equipment wear as the vibrator is operating in a more balanced condition.

6. Inspect equipment for balance and excessive vibration.

- An unbalanced machine can cause premature wire cloth failure.

- Equipment with a violent, uneven vibrating motion will cause stresses in the screen, and the cloth may actually break apart.

- Correct the unbalanced condition before continuing screening operation.
