Abstract
A mobile variable angle vibrating screen with the ability to process aggregate material in a horizontal orientation and at incrementally higher angles of inclination where changes in angles of inclination can be affected without the need to dismantle the vibrating screen and without the use of hand tools. The variable angle screen being configured: to blend output at all of the various operating angles of inclination, be transportable with a detachable bolt on feeder module; have an overhead feed conveyor which operates at a substantially horizontal configuration and at various operating angles of inclination.
Claims14
A mobile variable slope vibrating screen system for material processing comprising:
- a vibrating screen, configured to operate in a substantially horizontal orientation;
- a mobile chassis configured to support and transport said vibrating screen;
- and means for changing an angle of inclination of the vibrating screen so that said vibration screen can operate at angles from substantially 0 degrees to higher angles of inclination, with respect to said mobile chassis;
- wherein said means for changing includes:
- a base frame providing support to said vibrating screen and angularly adjustably connected to said mobile chassis;
- a hydraulic cylinder;
- an outer adjustable support leg;
- an inner adjustable support leg;
- a locking pin;
- and
- a hydraulic circuit configured to apply a biasing force to reduce slack.
A variable slope vibrating screen system for material processing comprising:
- a vibrating screen, configured to process aggregate material and operate at a plurality of operating angles of inclination;
- a base configured to support said vibrating screen;
- said plurality of operating angles of inclination of the vibrating screen comprises operating angles from substantially 0 degrees to higher angles of inclination, with respect to said base;
- a hydraulic cylinder;
- an outer adjustable support leg;
- an inner adjustable support leg;
- a locking pin;
- and
- a hydraulic circuit applying a biasing force to reduce slack.
The method of processing aggregate material comprising the steps of:
- providing a vibrating screen configured to process aggregate material and operate at a plurality of operating angles of inclination;
- providing a base configured to support said vibrating screen;
- providing a hydraulic cylinder;
- providing an outer adjustable support leg;
- providing an inner adjustable support leg;
- providing a locking pin;
- providing a hydraulic circuit configured to apply a biasing force to reduce slack;
- using said hydraulic circuit to apply a biasing force to reduce slack.
