Each of these streams is further split to evenly feed across the entire width of each of the screen decks
. Each screen deck
uses two-side tensioned panels of polyurethane screening media cloth with the appropriate aperture size to achieve the desired separation.
The steel reinforced injection-molded polyurethane PolyRail fastening system attaches to screen deck
frame support rails.
The overflow material (both on-size and oversize) then cascades over the screen's periphery, and onto the conventional screen deck
that scalps the balance of material in normal fashion.
One imbalanced-weight gyratory motor creates multi-plane inertial vibration to the screen deck
, controlling the flow path of material on the screen surface and maximizing the rate at which material passes through the screen.
This overview of American NuntdpaL Power Willow Creek, W.Va., hydroelectric project shows air-to-water chillers, insulated water storage pit, triple in-feed hoppers, washing screen deck
and insulated wet belt.
With the potential for 240 ft2 (22 m2) of screen area in one machine, the BigMax offers 12 feet (3.7 m) of screen deck
length, perfect for long retention time and accurate separations of product.
Two levels of lattice screen deck
and spa from neighbors.
The company believes accurate feed distribution across the 10 decks is critical, so the unit also incorporates a patent-pending feed splitter box to ensure the feed is evenly distributed across the complete width of each screen deck
. According to Metso, this machine arrangement delivers double the screening area relative to other fine screen technologies in a much more compact overall assembly.
The shapes can be flat slabs or pyramids, and each presents a different set of problems for the screen deck
. "The flat particle will pass a long slender slot, while the pyramid shapes can get caught in the aperture like little pegs, so each has to be handled differently.
The standard machine design provides a woven mesh, end-tensioned bottom screen deck
, but optional finger decks or Bofor bar decks are also available.
