The flip-flow screen with elastic screen surface has been widely used for screening fine-grained minerals due to its good performance [13, 14]. To achieve the best screening performance of flip-flow screen with simultaneously increasing lifetime, a better understanding of its dynamics is necessary, thereby optimizing structural design [15].

Flip-flow screens are increasingly used in the processing of fine wet coal. In this work, the vibration characteristics of an industrial-scale flip-flow screen with crank-link structure (FFSCLS) were investigated theoretically and experimentally. An improved kinematic model of FFSCLS was proposed and experiments are carried out to verify the …

The flip-flow screen is able to overcome the problem of screen clogging by indirectly driving the screen plate [17]. The main and floating screen frames move alternately, so that the elastic screen plate has a high vibration intensity (50 g), and the screen surface has self-cleaning functionality. When classifying 6 mm materials, the …

Results indicate that hysteretic damping of rubber springs can effectively solve the conflict between vibration strength and structural reliability of the flip-flow screen, since the low sensitivities of maximum stresses and the high sensitivity of accelerations to rubber springs damping are found. With the high G value of vibration, outstanding sieving …

The oscillation frequency at approximately 200 – 300 rpm is much lower, the stroke at 1.5″ – 2″ is much greater and the screen slope at 5° – 10° is much lower than that of vibrating screens. Support structures need to be `tuned' to accommodate the horizontal frequency, particularly when supporting multiple screens.

With the 30-50g ejection acceleration of screen panels, the flip-flow screen provides an effective solution for fine coal screening. However, the high ejection acceleration prolongs material particles residence time in the air, which leads to insufficient contacts between particles and screen panels, and finally resulting in the aggravation of particles …
