jar-bar feeder

The jar-bar grizzly feeder is a heavy-duty feeder which may form the bottom of the feed hopper of a primary crusher. It consists of a series of bars of elliptical cross-section with the major axes of adjacent bars at right-angles. Material is moved forward by the rotating bars, with a tumbling, rocking motion which makes this type of feeder suitable for applications where fines and clay have to be removed from the feed.
