-
Ease of Maintenance - perforated
screens will not stretch so no re-tensioning is required during
service life of the screen.
-
Screen Frame Protection - blanked
areas are designed and engineered into perforated to protect
screen support frame.
-
Greater Choice - round, hexagon,
square or slotted; straight or staggered centers; precise,
flexible configuration and virtually infinite patter
possibilities.
-
Wider Material Thickness Range -
wide range of thickness for each opening size. Bar width and plate
thickness can be separately specified to attain desired open space
while maintaining increased wear life.
-
Excellent Screening Efficiency -
perforations are staggered in direction of flow. The percent of
open area of perforated screen plate equals or exceeds the percent
of open area in wire cloth in many cases.
-
Resistance to Plugging - screen
plate features clean walled, conical, closely and uniformly spaced
perforations. This results in a minimum of blinding, because
material is always passing through a progressively larger opening.
-
Maintenance of Sizing Accuracy -
since screen plate is a single unit there is no wire movement
which would interfere with sizing accuracy as the screen wears
through.
-
Greater Bulk/Less Breakage -
greater effective cross-sectional area compared to wire cloth
screen. This translates into greater screen life with no open area
reduction.
-
Fewer Wear Causes - perforated
screen plate and wire cloth wear from material passing over and
through the screen. Wire cloth also wears from wires rubbing each
other at junction points.
-
Greater Strength/Equivalent Weight -
perforated screen plate and wire cloth with similar open areas
have negligible weight differences.
