The Vibration Screen is composed of a hopper, an oscillating chamber, a coupling, and a motor. The oscillation chamber is composed of eccentric wheels, rubber software, main shaft, bearings, etc. The adjustable eccentric hammer is driven by a motor to reach the centerline of the main shaft, generating centrifugal force in an unbalanced state, changing the strength of the material and forming a track vortex inside the screen. The amplitude of the heavy hammer adjuster can be adjusted according to different materials and screens
