Vibrating Screen
Installation and Maintenance |
| |
|
|
|
|
You can dramatically increase the life of your wire
cloth screens and do a more efficient job of material screening by following these steps. |
|
|
|
|
Screen
Installation |
|
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 deck. |
|
|
|
|
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 the 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 have occurred. |
|
|
|
|
|
|
|
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 damaged parts in
the screen assembly.
|
|
|
All hole positions on the clamping bars
must be utilized.
|
|
|
|
|
3. |
Maintain the 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
an even and tight screen fit.
|
|
|
|
|
4. |
Change your channel rubber frequently. |
|
|
Remember that channel rubber will wear
from the bottom up as well as from the 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 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.
