Jaw Crusher Main Components Introduction

Jaw Crusher Eccentric Shaft Bearings : These bearings are typically roller in style and usually have labyrinth seals and some are lubricated with an oil bath system.

Jaw Crusher Sides------Cheek Plates : The sides of the jaw crusher are logically called cheeks and they are also covered with high-strength manganese steel plates for durability.

Toggle Plate------Protecting the Jaw Crusher : The bottom of the pit man is supported by a reflex-curved piece of metal called the toggle plate. It serves the purpose of allowing the bottom of the pit man to move up and down with the motion of the eccentric shaft as well as serve as a safety mechanism for the entire jaw. Should a piece of no crusher material such as a steel loader tooth (sometimes called tramp iron) enter the jaw and be larger than the closed side setting it can't be crushed nor pass through the jaw. In this case, the toggle plate will crush and prevent further damage.

Tension Rod------Retaining the Toggle Plate : Without the tension rod & spring the bottom of the pit man would just flop around as it isn't connected to the toggle plate, rather just resting against it in the toggle seat.

Jaw Crusher Adjustment: Depending on the disposition of the material being crushed by the jaw different maximum-sized pieces of material may be required. This is achieved by adjusting the opening at the bottom of the Crusher.
