XZS series vibrating sieve uses vertical motor as the source of vibration, equipped eccentricity hammer on the both sides of the motor. Adjust the phase angle on the both sides of the top and bottom can change the movement orbits (Motion Trajectory) on the surface screen. When the material is fed in to the centre of top screen, it vibrates around its central axis in a gyratory motion, promoting the material across the screen when it is flowing to the margin of the sieve. Undersize material passes rapidly through the screen and over sized material get continuously discharged through a special outlet.
