In this paper, a novel rigid-flexible coupled ultra-high elastic screen surface was proposed. Then vibration test was conducted to investigate kinematic characteristics of the screen surface. Moreover, a high-speed camera device was utilized to study deformations of the screen surface and the mechanism of strengthening looseness and overcoming plugging. Furthermore, the screening performance of screen surface was investigated. The obtained results show that the maximum acceleration and the displacement of the proposed screen surface can be as high as 27 g and 21.37 mm, which are 8.82 times and 7.32 times of the side plate area, respectively. Accordingly, the screen surface can produce strong impact on the sticky and moist materials, so as to make materials loosen and overcome the plugging problem of the screen surface. After optimizing the parameters, the screening efficiency can reach the maximum value of 85.41% and the content of the total misplaced material is 7.07%.
