High freuency screen consisit of vibrating exciter , slurry distributor , screen frame ,machine framework, suspension spring and sieve.

 

High frequency screen has the advantage of high efficiency , small amplitude and high frequency of screening . It differs from the conventional screens with breaking of the surface tension of pulp and small granularity high speed vibrating on sieve cover and accelerates the separating of large density useful mines and increase the contacting probability of the materials smaller than ouput granularity and the sieve pore, therefore create food condition to make the smaller size materials get throught the sieve pore together with the slurry especially the big desity materials.
