ABSTRACT:
A vibrating screen apparatus includes a frame and a screen having a first end coupled to an anchor beam which is rigidly coupled to the frame. The apparatus also includes a tension control assembly coupled to a second end of the screen for tensioning the screen to substantially a predetermined tension. The tension control assembly is rotatably coupled to the frame spaced apart from the anchor beam. The tension control assembly changes the tension of the screen upon rotation of the tension control assembly relative to the frame about an axis of rotation. The apparatus further includes an adjusting mechanism for moving the tension plate in a direction normal to the axis of rotation of the tension plate to compensate for nonuniform tension of the screen.
