McLanahan Universal Jaw Crushers are overhead eccentric jaw crushers that continuously reduce material as it passes through the crushing chamber with its aggressive force feed action as the movable jaw compresses inward and downward. The sharp primary blow at the top of the chamber reduces material instantly, while a secondary crushing action at the bottom further reduces material to the predetermined output size. Universal Jaw Crushers offer a compressive stroke that is nearly equal at both the top and bottom of the chamber, producing more spec material at a lower cost per ton.
