According to differenct screening requirement, different inclined screen angles are selectable. The upward design of the screen surface inclination angle forms a slurry pool at the feed end so its static pressure source helps the penetration of liquid slurry through sieve with high material handling capacity; With double motor self-synchronous vibrator, two vibration motors produce linear vibration trajectory and promote the transport, dehydration and discharge of oversize products (coarse-grained materials) through the synchronous, reverse rotation; adopt shock-absorbing steel spring support, low noise, low power consumption, small equipment dynamic load; use hard wearing polyurethane screen panel with high porosity, good dewatering performance and long service life.
