Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first overhead eccentric jaw crushers. Since that time, this robust design has continued to be the basis of the Universal Jaw Crusher design. Today it can be used in a variety of operations, including rock quarries, sand and gravel, mining, recycling, construction aggregates, and by road building contractors. Materials processed by the Universal Jaw Crusher include limestone, granite, basalt, gravel, gold ore, copper ore, iron ore, limestone, gypsum, concrete rubble and more.
This overhead eccentric jaw crusher continuously reduces 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.
In addition to the standard jaw crusher design, McLanahan also produces the H-Series, which features adjust-on-the-fly capabilities. With its hydraulic adjustment option, the Universal H-Series Jaw Crusher saves time when adjusting the closed side setting to allow for wear and maintaining a constant product output. The crusher eliminates the downtime associated with shim adjustments. It also features hydraulic cleaning and automatic hydraulic tramp iron relief and can reset itself to the previous position without operator intervention.
