Investigation of the Process of Separation of Fibers From Seeds During Roll Ginning

Abstract In the initial position in process of roll ginning, seed is drawn to slot contact gap knife-drum due tension fibers. Subsequently, struck with a certain impulse. The separation fibers from after impact beater occurs sequentially, not simultaneously. As result theoretical and experimental studies, optimum frequency shock pulse on ( f = 18-20) was found be most technologically successful terms providing best quality indicators seeds Beating resonance mode allows reduce magnitude impulse seed, leading reduction degree damage seeds. At this moment, at end strand move only under action an elastic restoring force. active part fiber bundle section dynamic can as little 0.001 or less. average value compliance coefficient for raw cotton variety BA-440 determined experimentally. This allowed determine stiffness volatiles indirectly. According parameters obtained, state system practically falls into region parametric resonance, where motion unstable. means that damaged enlarge significantly beater, causing separate
