Flat Screen Design Improved
Cedarapids/ElJay Flat Screens have
undergone a number of engineering changes aimed at further improving overall screen
efficiency and product performance.
Side plate material has been upgraded to a high strength,
low alloy, fine-grained steel providing up to 40% additional strength. New side
sheets allow for increased ability to withstand wear, stress and fatigue for the most
rugged of applications. The new high strength steel also maximizes clamp bar tension
without deflection.
A 25% increase in the thickness of the screen's clamp bars
eliminates distortion and maintains uniform wire cloth tension for increased screening
efficiency. The adoption of square slotted holes in the clamp bar (versus typical square
holes) allows for vertical movement of the clamp bolts for precise fastener angle
orientation and automatic adjustment to various wire cloth thicknesses.
The new design incorporates spherical washers instead of
typical alignment washers, eliminating all welded stress concentrated on the side sheets.
In concert with the slotted clamp bars, the spherical washers ensure reduced clamp bolt
angle, which eliminates clamp bolt fatigue and breakage.
Deck frames now incorporate bolted double x-braces for
enhanced durability. All models, with the exception of the four foot wide screens, have
been modified to accentuate and improve the profile of the deck crown. This promotes a
more uniform distribution of material over the deck for greater screening efficiency and
improved screen cloth wear life.
Due to the increased demand for polyurethane screen media,
standard flat decks have been designed for models FSG720, FSG620, FSG616 and FSG516. The
flat deck is available in lieu of the standard crown deck and will accommodate most
polyurethane supports.
A new gear set for the FSG620 screen offers notable changes
in alloy, cut and polish. The new set significantly increases gear wear life.
Gearcase and hub modifications have been implemented on the
FSG720 and FSG620. Modifications are aimed at improving oil flow to bearings and reducing
operating temperatures for longer in-service life.
