Twin Shaft Vibrating Grizzly / Vibrating Grizzly Feeder
When the Grizzly is at rest, the extreme point of the eccentric portion of the two shafts point vertically downwards. As the Drive Eccentric Shaft is rotated at about 800 r.p.m. by an electric motor, the Main Body is set to an elliptical and forward jumping vibrating motion, caused by the counter rotating motion of the two highly eccentric shafts positioned at different levels below the Main Body. Hence, the boulders on the deck begin sliding downwards, accelerated by its stepped profile and the Main Body's inclination.
The distances between the castings enable the segregation. In case of multiple decks, more than two segregations are obtained. All segregations are separately collected and discharged by the chute arrangement in front of and below the Main Body.
