Sieve bend screen

The dewatering capacity of a wedge wire cross flow sieve bend screen is primarily influenced by the screen width, the slot opening, and the wire size (width). The chart below shows typical dewatering capacities in US gallons per minute (GPM) per foot of screen width. Actual capacity varies depending on the feed content and desired efficiency.

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
