FIELD: equipment for separation of material into fractions, may be used in construction material industry and other branches of industry. ^ SUBSTANCE: elastic sieve for screen has rigid frame, supporting members, longitudinal beams and elastic sieve sheets. Supporting members are equipped with U-shaped slots for fixing on rigid frame so as to move in longitudinal plane, and flat shaped protrusions for securing in transverse plane within open slots provided on edges of sieve elastic sheets. Longitudinal beams are located in longitudinal plane within open slots on edges of elastic sheets. In order to impart compressive deformation to sieve sheets, sieve is equipped with device for compressing elastic sheets, said device being made in the form of nuts positioned so as to be screwed into longitudinal beams at both sides and providing bolted connection for retaining of supporting members. ^ EFFECT: prolonged service life of screen sieve, increased wear-resistance, reliable fastening and simplified adjustment of compressive deformation applied to sieve sheets. ^ 6 dwg |
