On Dynamic Analysis of Rotatory Vibrating Screen and Material Being Sieved

In Chinese industry, straight-line and circular vibrating screens have found increasingly widespread use. More efficient rotatory vibrating screcns have begun to appear on Chinese market. In this paper the authors present a theoretical analysis of motion of both rotatory vibrating screen and material being sieved. Such a theoretical analysis is believed to be useful in designing better rotatory vibrating screen in China.The main results of theoretical analysis are:(1) The displacement at any instant of any point on the screen surface of rotatory vibrating screen can be computed with eq .(13). Different points move in different elliptical paths in space.(2) The translational amplitude and rotational amplitude of rotatory vibrating screen can be rcspcctivcly computed with eqs.(5) and (6).(3) The displacement of any point in material being sieved at any instant can be computed with eqs.(16) and (17). For such computation, the authors complete a computer program. Loci of particles in material being sieved arc approximately spiral as shown in Fig.6.
