Progress Eco Pro-Slot - Flat Sieves for Wedge Wire Screens
Flat sieves are flat panels of welded profile wire, fixed to a frame and adapted to assembly. Depending on the kind of application, flat sieves can be divided into: Sieves working in dynamic systems: panels to be incorporated in vibrating sieves, special reinforcement depending on the sieve load is necessary, special finishing to guarantee secure, long working time, and proper fixing. Sieves working in static systems: do not require any special reinforcements, can work as bottoms and decks in tanks and storage reservoirs and sumps.
The flat welding technology ensures flatness within small tolerances. It does not weaken joints, as in the case of straightening screens welded on a round.
Arch sieves are mainly used for dewatering and separation of solid particles from liquids. Depending on the application character, they can be divided into arch sieves with gravitational loading or arch sieves with pressured loading.
The application of arch sieve provides:
- uniform flow onto the sieve (usage of the whole sieve surface)
- high speed of flow onto the sieve
- increased classification effectiveness and efficiency (due to the possibility of applying the working wire at a defined
Gutter sieves are used as bottoms of screw conveyors, where in addition dewatering or separation is required apart from transportation.
Conical sieves and conical baskets are mainly used in centrifuges. They can be divided in two categories depending on their work character:
Working in dynamic system
- for all kinds of centrifuges,
- with self supporting structure consisting of ribs, rings, flanges which constitute an integral part of the sieve construction. After a period of exploitation the whole basket has to be replaced:
- without the supporting structure
- as screening insert for non disposable structural frames. The only thing to be replaced is the screen insert.
Working in static systems- centrifugal dewatering screens
- filter cartridges
- filter elements for pipelines.
