sieve bend

sieve bend screening unit is the answer to many de-watering, sizing, and wastewater cleanup problems. Typical uses are sewage treatment, laundry wash water clean-up, poultry, fish, fruit and vegetable wastewater processing, minerals processing, coal preparation, paper production, textile plants, and many more. A sieve bend consists of a concave curved profile wire screen mounted in a frame with the screen openings perpendicular to the flow. A curved screen has greater capacity than a flat screen due to forces exerted as material flows against the curved surface.

Sieve bends are also known as DSM screens, after Dutch State Mines, who introduced the sieve bend as a static sizing screen having ten times greater capacity than conventional vibrating screens.

Applications for Sieve Bend Screen:

The sieve bend screens are mainly used for the water-treatment , water well drilling ,oil well drilling ,mineral processing, coal-cleaning plant ,sewage treatment and other industries,water, oil or gas filter and other filtration equipment.

Advantages for Sieve Bend Screen:

A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.•A “V”shaped profile wire which avoids clogging and ensures an uninterrupted flow.

A uniform and efficient well development due to the continuous slot opening.

Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.

Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
