sandra xu 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. Larger particles continue down the screen surface, with much of the liquid removed. Separation size is considerably smaller than screen openings, usually about one half the opening sizes. Sieve Bend Features: Energy Efficient - operates with no moving parts and with no energy input. Space Efficient - treats up to 122 litres per second per square metre of floor space. Quiet Operation - no moving parts means no mechanical or electrical vibrations. Accurate Sizing - can be used for sizing solid particles down to 0.2 mm (0.008"). Low Maintenance - the profile wire screen resists clogging by near-size particles, and the all-stainless steel construction ensures a long, corrosion-free installation.
