Vibration device analysis model was established in the ADAMS, then through the motion simulation analysis got all kinds of waste plastics movement displacement locus and spacing diagram on the screen surface, so the motion parameters was optimized. Waste plastics composite separation device was developed, what improved the precision and efficiency of plastic separation.]]>Dan, L., W. Jing and L.
