  • Portable screening plant with displaceable eccentric
    Patent number: 6669026
    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.

  • Multiple screen system
    Patent number: 6000553
    Abstract: A screening plant including a housing to which first and second screen boxes are reciprocatably mounted. The screen boxes are coplanar and the inner peripheral edge of the first box is adjacent the inner peripheral edge of the second box. Separate prime movers, such as hydraulic motors, are drivingly linked to the independently mounted screen boxes. The screen boxes are separated by a gap over which a beveled cap is mounted.
