INDUSTRY: Mining, Aggregate, Recycle
Bare Jaw Crusher
Bare Jaw
Our world-renowned jaws lie at the core of Lippmann’s product offering and have been manufactured in Milwaukee, WI, since 1923. Fabricated with extra heavy ribbed steel plate construction, Lippmann jaw crushers have proven time and again they provide maximum strength, durability, and reliability at the lowest cost of ownership in the industry.
Frames are stress-relieved before machining to ensure uniform heavy-duty strength and trouble-free operation on a stout, easy-to-move truck frame. Jaw crushers also feature an oversized shaft, tapered roller bearings, reversible jaw dies, and an oil-bath lubrication system.
Highlights
Heavy-duty, oversized heat-treated shafts forged of special alloy to handle overloads and hard material
Radial thrust tapered roller bearings–the best design for absorbing and withstanding shock, radial, and thrust loads
Longer jaw length to provide increased crushing area, steeper nip angle and increased capacity
Curved jaw dies to provide non-choking crushing action, reversible for increased wear
Rugged frame with heavy-ribbed steel plate construction at stress points, stress relieved by heat treating before machining
Protected pitman hub with rock rib
Dynamically balanced flywheels reduce vibration
Toggle plate is set at an optimum angle for maximum crushing
Positive setting adjustment shims provide easy change of discharge opening with aid of hydraulic pumps
Lubrication easily checked; positive oil-level gauges assure correct lubrication of bearings
Inside contact surfaces are fully machined
