Influence of vibration mode on the screening process
The motion of a vibrating screen can be defined as three types, linear, circular or elliptical, depending upon the trajectory. Fig. 1 shows that λ is the amplitude and β is the vibration direction angle of the model. The simulations use an improved DEM dry contact soft-sphere model [13], [14]. Fig. 2 shows that k n and d n are the normal stiffness and normal damping; k t …
