A three-dimensional model of a vibrating screen was established. A DEM simulation based on this model offers insight into the entire sieving process. A stepwise optimization method was employed to explore the optimal screen surface shape that has excellent sieving performance, and a new type of curved screen was developed.
The Structure model of three-dimensional excitation circular vibrating screen was established. Then a dynamics analysis based on Lagrange equation was used to analysis this model.
As mentioned above, three different vibration screens (variable linear vibration screen with flexible screen face, variable linear vibration screen with fixed screen face, and linear vibration screen) can be obtained by changing the former built simulation model exciting force position and the connection type of rod and frame.
Rotary Vibration Screen Working Principle. The rotary vibrating screen uses a vertical vibration motor as the exciter. The upper and lower ends of the vibration motor are equipped with eccentric weights, which convert the rotational motion of the vibration motor into horizontal, vertical, and tilted three-dimensional motion and then transfer this motion …
