 |
| Slag
Plants |
|
| Phosphate
Rock |
|
| Iron
Ore Mines |
|
| Copper
Mines |
|
| Gold
and Sliver Mines |
|
| Crushed
Stone Quarries |
|
| Sand
& Gravel Plants |
|
| Clay,
Asbestos & Gypsum |
|
| Lightweight
Aggregates |
|
| Coal
Preparation Plants |
| Advantages of Heat-Treated Perforated
Screen Plate |
- Economical
The screens are heat-treated after perforating, for hardness and
abrasion resistance, thus giving a very long screen life. This
results in less plant shutdown time for replacements and re-tensioning,
less stocking of inventory of screen and reduced costs.
- Accuracy
Screening with these screen plates results in more accurately
screened products. Perforations remain uniform and there is no
stretching of the screen. There is a choice of square, round,
hexagonal, slotted perforations.
- Efficiency
As the open area of the perforated plate usually equals or exceeds
the percentage of open area in wire mesh /cloth and the perforations
are staggered in the direction of the flow of material this ensures
greater screening efficiency.
- Less Chance of Blinding
Perforated Screens are slightly tapered to resist blinding and
plugging and are easier to patch.
