Sieve Bend Screen – DSM Screen

The sieve bend screen – also called bend screen – comprises a curved screen for filtration. The bend screen provides filtration by guiding the particles along with the curved sieve filter screen.

The shape of the sieve bend screen offers a high filtration rate because of the forces exerted by the particles in the flow over the sieve bend. Thus, it is used for different applications that benefit from bend screen geometry.

The Sieve Bend is also known as a DSM Screen, as it was developed by the Dutch State Mines. Sieve Bend Screens are useful for sizing and dewatering applications to separate solids from liquids, as well as solid/solid separation for dry feed applications.
