Abstract
A compact mobile variable angle vibrating screen with a suspension and dampening system configured to rapidly accommodate variable angles and exhibit acceptable vibration levels; especially during power up and power down surge vibration at the variable angles. The system comprises a group of bi-directional dual pivot leg vibration damper mechanisms, including nesting tubes, one with holes for receiving pins and the other with a semi-circular cutout at the bottom edge.
Claims6
A variable slope vibrating screen for material processing comprising:
- a frame;
- a support structure which is configured to be adjusted to variable angles with respect to said frame;
- a variable slope vibrating screen configured for sorting aggregate by size, said variable slope vibrating screen being supported at variable slopes by said support structure;
- a discharge output configured for creating a pile of sorted aggregate;
- and
- a hydraulic system configured to apply a biasing damping force which is directed for biasing a portion of said support structure, so as to reduce relative movement between said frame and said support structure;
- further comprising an accumulator for maintaining said biasing damping force over a period of time, despite pressure reducing leaks in said hydraulic system.
