Grizzly Bars. As the ore is fed to the crusher, it passes over the grizzly bars, and the finer pieces drop through into the mill ore bin. The grizzly is made of wear resisting wedge shaped bars easily replaced if necessary. Grizzly Bars are punched and held in place by steel rods passing through the holes.
Fitted with picks, the crusher drum breaks apart rock layers consisting of basalt, granite or materials of comparable compressive strength, as well as mixed soils, while compacting the ground to a great depth. Depending on the material, a much smaller number of excavators, crushers and transporters are required. Precrushing and crushing
