  • A Numerical Study of Separation Performance of Vibrating Flip .

    Vibrating flipflow screens (VFFS) are widely used to separate highviscosity and fine materials. The most remarkable characteristic is that the vibration intensity of the screen frame is only 2–3 g (g represents the gravitational acceleration), while the vibration intensity of the screen surface can reach 30–50 g. This effectively solves the problem of the blocking screen aperture in the ...
