After the vibration rolling frame reciprocates, it drives the rolling shaft and the rotary milling hammer to reciprocate within the set stroke. During the reciprocating vibration of the rotary milling hammer, the set speed of rotation can occur. The rotary vibration motion of the rotary milling hammer occurs, so that the electrolytic aluminum waste slag to be crushed is cyclically hammered and crushed.
