The working principle of the jaw crushers is very simple. Powered by a diesel or gas motor, the jaw crusher brakes materials in a crushing chamber. In the overhead eccentric jaw crushers, the pivot joint is located at the bottom of the chamber, while at the double toggle crushers, the pivot joint is on the top. The double toggle jaw. Learn More
Reversible manganese jaw dies for maximum wear life. Large, spherical, self-aligning roller bearings. Isolated, close running annular/labyrinth seals protect bearings from dust and water. Removable pitman/bearing assembly for maintenance ease. Steep pitched toggle plate for maximum horizontal pitman movement. Hydraulic or manual shim adjustment.
In jaw crushers of the type wherein a pair of relatively movable jaws are separated by an intervening crushing chamber and at least one of the jaws is pivotally suspended from an overhead rotary driving shaft journalled in axially spaced stationary bearings carried by the crusher frame, while the jaws are movable to efiect crushing by one or more eccentric portions on each suspension shaft ...
On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double roll spherical roller bearings. The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side (called a stationary jaw die due to the action of a toggle plate), and the second is a
