Dynamic Modeling of a Vibrating Screen Considering the

For example, a change in the slope of 1° can cause a decrease of 1-2% in the screening efficiency [1, 8, 9], whereas a change of 1 mm in the vibration amplitude can cause a loss of between 5% and 10% of the screening efficiency [1, 9, 10]. These efficiency losses depend on the vibrating screen design, ore characteristics, and operational ...
