Wedge Wire Porducts

Mounting of Wedge Wire Panels on Vibrating Deck Frame 

While mounting of Wedge Wire Screen Panels, tit ost care should be taken that all screen panels are rigidly fixed on the deck frame. The cover rail of Flats used for bolting the panels on the deck frame must not be put directly on the panel surface. Rubber packing in between must be provided.

Sufficient rigid fixing is necessary so as not to develop any secondary vibration (flexing) under operation as, this will result in premature failure of screen panels. To ensure the rigid fixing during operation periodical check of tightening bolts is recommended.

INDUSTRIAL APPLICATIONS

Wedge wires can be employed in almost all industrial processes which require very fine and uniformly accurate aperture, combining rapid discharge of material and high mechanical strength. Some of the specialized applications of these screens are given below:
 

1. Coal and Coke Washeries

Flat and curved wedge wire screens and Centrifuge Baskets with suitable re-inforcements are used for dewatering processes on stationary and moving frames, suction filters and centrifugal driers.

2. Ore Beneficiant Plants

In Iron and other Ore benificiant plants, wedge wire flat screens, Curved screens and Centrifuge baskets of fine and very fine aperture are used for efficient Dewatering and recovery of fines.

3. Sugar Mills.

Flat, curved and cylindrical wedge wire screens are used for Juice Filtration and Bagasse Separation drainage in tanks in conjunction with scraper conveyors as well as for draining crushed sugar cane supply in D.S.M. Screens. 

4. Cement, Chemical and Fertilizer Plants. 

Flat panels, Curved wedge wire screens, Cylinders and Centrifuge baskets with cylindrical type, conical type and pusher type have many and varied applications in these industries.

5. Cellulose, Wood and Straw Pulp and Board Industries

Wedge Wire cylinders, Flat panels and Centrifuge baskets are used for preliminary screening for knot catchers and for efficient fibre recovery Wedge wire screens ensure greater efficiency than the conventional perforated or machined slotted plates.

6. Sewage, Effluent and Water Treatment 

Flat wedge wire decking in final settlement tanks provides tertiary treatment for the reduction of suspended solids. It is also the medium used in a technique for the consolidation of sludges where the rate of filtration is controlled at low operating pressures. Sewage, aluminium hydroxide, iron hydroxide and other industrial sludges are being successfully dewatered on wedge wire.

7. Malt & Food Grain Drying Floors & Solvent Extraction Plants

Wedge wires are also used for making up ventilation floors and has been found very suitable for malt kiln flooring, grain drying flooring and air curtains. Vertical type Solvent Extraction Plants also uses Wedge Wire Screens for high efficiency of extraction.

8. Salt Washery

Cylindrical and Conical type centrifuge baskets of fine aperture to suit any existing centrifuges having precise aperture, high mechanical strength and corrosion resistance are extraordinarily being used in modern salt washeries. Curved screens are also being used.
