Behavior of maize grains on the three-dimensional
The above studies show that manifold forms of multidimensional motion of sieve could be obtained by cam, crank rocker, vibration exciter and other mechanisms. The cleaning performance was improved by these unique forms of motion. However, there is no study on three-dimensional translational vibrating sieve, which is driven by a cylindrical cam.The present studies for the screening theory of granular materials mainly focus on simulating the screening process by using the discrete element method (DEM),the screening experiment for choosing optimal vibrating parameters (amplitude, frequency, inclination angle, etc.),the trajectory of particles bouncing on a vibrating screen and theThe Nonlinear Dynamic Behavior of a Particle on a Vibrating Screen
