高频筛

高频筛由激振器、矿浆分配器、筛框、机架、悬挂弹簧和筛网等部件组成。高频筛效率高、振幅小、筛分频率高。与普通筛分设备的原理不同，由于高频筛采用了高频率，一方面破坏了矿浆表面的张力和细粒物料在筛面上的高速振荡，加速了大密度（比重）有用矿物和析离作用，增加了小于分离粒度物料与筛孔接触的概率。从而造成了较好的分离条件，使小于分离粒度的物料，特别是比重大的物粒和矿浆一起透过筛孔成为筛下产物。

high-frequency screen consists of vibration exciter, ore pulp distributor, screen frame, machine frame, suspension springs and sieve, etc.features: 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 vibration on sieve cover and accelerates the separating of large-density useful mines and increase the contacting probability of the materials smaller than output granularity and the sieve pore. therefore produce good condition and make the materials smaller than the output granularity, especially the big-density materials and pulp get through the sieve pore together.
