Jaw Crushers by Pennsylvania Crusher Brand

Jaw Crushers reduce unusually hard, tough and/or abrasive rock, as well as ferroalloys and glass, which cause excessive wear to other types of crushers.

Many types of crushers use rotating hammers and other crushing elements to reduce materials by impact, shear or attrition. Jaw Crushers, however, crush by compression of the material between two opposing surfaces — the jaws.

Pennsylvania Crusher brand Jaw Crushers are available in both Double Toggle and Overhead Eccentric models. To read more about each type of crusher, download the product sheets below:

Double Toggle Crusher

Pennsylvania Crusher double toggle jaw crushers have won worldwide acceptance from the glass industry where they are recognized as the standard due to these important features:

Positive crushing of virtually all shapes and sizes of cullet to the desired particle size. Our cullet plates are specially designed for cullet crushing and configured to prevent any glass from falling through without being crushed.
Strictly compression crushing which provides jaw service life several times longer than with other methods.
Minimal dusting due to the absence of rubbing actions, minimizing the need for protective devices for employees as well as shielding for nearby equipment.
Enclosed lubrication for complete protection from damage by contamination.
Tramp protection via a safety release mechanism which protects both the crusher and the motor from damage if uncrushable material should enter the crushing chamber.

Overhead Eccentric Crusher

The Pennsylvania Crusher overhead eccentric jaw crusher is the most massive and rugged jaw crusher avilable today. Its many unique features and advantages make it the most cost-effective crusher of its type.

The crushing chamber, for example, is longer than is found in any other design. This provides a far more efficient angle of nip, enabling the jaw plates to grab material more effectively and produce higher capacities than other machines with the same size feed opening.

Made of high-strength cast alloy steel, these extra long jaw plates are designed for maximum crushing capacity. Their high speed compressive action produces effective crushing across the entire jaw area and throughout the entire crushing chamber. The massive cast steel pitman and forged alloy steel eccentric shaft are supported by four anti-friction roller bearings.

Advantages & Benefits of Jaw Crushers:

Minimal abrasion or gouging of the jaw plates, often less than 25% of other jaws
Relatively low fines production
Virtually all of the power is used for crushing
Do not require massive and costly foundations
Desirable for portable applications
Strictly compression crushing which provides longer jaw service life
Minimal dusting
Enclosed lubrication for complete protection from damage by contamination
Tramp protection via a safety release mechanism
