Vibrating flip-flow screens (VFFS) are widely used to separate high-viscosity 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 …
Flip-flow screening is an important method for classifying fine particles. As the lower limit of classification decreases during the screening process, the influence of particle-size characteristics becomes more significant. In this study, a laboratory prototype device of flip-flow screen (LPDFS) based on displacement excitation was built.
In principle, a flip-flow screen is a subclass of other high frequency vibratory screens. Flip-flow screens work through the combination of a double vibration principle and a flexible polyurethane-type screen media. The dual-vibratory forces work to apply linear acceleration to the materials traveling across the screen. Vibrations are ...
