Abstract: A vibration-reducing eccentric weight system mounted to the driveshaft of a screen box in a portable screening plant with the eccentric weight system's center of gravity on the driveshaft's axis of rotation. The eccentric weight system includes a weight that is radially slidably mounted to the driveshaft, but biased so that its center of gravity is spaced from the driveshaft's axis of rotation during slow and no rotation. Upon rotation above a preselected speed, the centrifugal force displaces the weight radially outwardly. This causes a gradually increasing vibration corresponding to gradually increasing distance between the weight's center of gravity and the driveshaft's axis of rotation.
