Abstract:

Based on the concept of force-centre of double-axis inertia vibratingscreen put forward for the first time, this paper has analyzed and discussed some problems of calculation in designing double-axis inertia elliptic vibrating -screen. It has also given some calculating examples and compiled corresponding computer programs, which can be applied to the research and design of vibrating-screens. According to the method presented in the paper, "PTZS" vibrating-screen with parallel motion of elliptic locus has successfully been designed and made

Key words: Vibrating-screen with parallel motion of elliptic , Force-centre
