ZS series vibration sieve consists of Hopper, vibration Chamber and coupling and motor. Oscillation there are eccentric wheel, rubber software, spindle, bearings and other components. Adjustable eccentric hammer is driven by motor and pass on to the spindle center line, in a State of unbalance centrifugal force, material strength changes form in the screen track spiral. Amplitude of the hammer regulator can be adjusted according to different materials and sieve.
