Vanguard Jaw Crusher

March 28, 2014

Redesigned Vanguard jaw crusher has replaceable wear jaw die seats and barrel protector plates parts for an improved life cycle. Jaw die retention wedges hold the jaw die in place, providing easy access to the jaw die and efficient removal and replacement. In addition, the new design contains lifting holes on all Vanguard jaw dies so lifting lugs are no longer required to be welded. These advancements yield less downtime between jaw die replacement and other maintenance intervals, the company says. The crusher now uses hydraulic cylinders instead of shim plates to adjust the crusher’s closed side setting.

The five largest crushers crush with a 1 1⁄2-inch stroke. The aggressive toggle plate angle gives more movement to the bottom of the pitman, resulting in more crushing per stroke. Its flywheel inertia allows the crusher to function while reducing energy input. By using large, dynamically-balanced flywheels, peak horsepower requirements are reduced, yielding greater efficiencies and fewer fuel costs.
