PURPOSE: A grizzly selection device is provided to form a grizzly bar into a round shape, thereby relieving the impact which is generated when ore is dropped. CONSTITUTION: A grizzly selection device comprises a main plate(100), a support unit(200), multiple grizzly bars(300), an eccentric weight(400), and a drive motor. The support unit is connected through an elastic unit as a medium to the edge of the main plate in order to elastically support the main plate. The multiple grizzly bars are installed on the main plate vertically in multi stages. The eccentric weight rotates to vertically vibrate the main plate. The drive motor rotates the eccentric weight. |
