Dynamic characteristic analysis of vertical screw conveyor in

The capacity of vertical screw conveyor is affected by many factors, such as feed quantity, screw rotational speed, material filling rate, screw pitch, etc. Owen et al. 11,12 studied the influence of different angles, rotational speeds and filling rates on the conveying performance using DEM, and the predictions of characteristic parameters, Recently, mill chatter has been recognized as the bottleneck in high speed rolling. Therefore, it is important to investigate the vibration mechanism and vibrational stability in a tandem cold rolling mill. Many previous experiments were performed using a mass-spring structure system to study chatter characteristics in cold rolling.Dynamic analysis of vibration stability in tandem cold rolling mill
