Sieve Bend Screen is a high efficiency curve separate madia by wet material pressure.
Vee wedge wire screen have high strenthen and carrying capacity,the V wire make sure the screen will not block,easy clean,working very long time.The Wedge wire parabolic filter made by Nanrui with high accuracy and can instead of all Johnson screen.
Material: AISI 302,AISI 304,AISI 304L,AISI 316,AISI 316L.,polyester frame.
Actual capacity varies depending on the feed content and desired efficiency.
Screening efficiency and solids capacity are directly related to the length (arc length). Longer arc lengths should be considered for feed containing a high percentage of solids.
The dewatering capacity of cross flow dewatering screens such as the sieve bend can be greatly increased by tilting the wedge wires. The wedge wires are tilted 2 to 7 degrees depending on the wire size and slot opening.
The effective range of slot openings for a gravity-fed cross flow sieve bend screen is generally considered to be .015" to 1/8". The installation angle of a sieve bend screen is usually 50 to 60 degrees from the horizon.
The point of size separation is approximately 50% of the slot opening size.
Advantages of Sieve Bend Screen
flatness to within tight tolerances
no weakening of the welds, because of flattening (and no stress corrosion problems as a result)
accurate distance between support profiles
possibility of different support wires in one screen
possibility of variable spacing between support wires in one screen
