This action draws in the material ore into the gap set, crushing the material between the fixed and swing jaw plates to size set. The cheek plates protect the inside of the crusher from wear and keep swing and fixed jaw plates in position. The top of the swing jaw is supported on bearings by the eccentric shaft. The

Secondly, the motion of the swing jaw, at the top of the crushing chamber is, proportionately, smaller than the movement at the top of the gyratory chamber. The reason for this is that the distance from the top of the crushing chamber to the fulcrum-point—as compared to the total length from discharge-point to fulcrum-point is smaller in the ...

The Jaw crusher gets its name from the type of crushing surface used. This surface is literally two jaws. One of which is a STATIONARY OR FIXED JAW. The other is called a SWING JAW. The ore enters from the top and the swing jaw squeezes it against the stationary jaw until it breaks.

A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, "swing" jaw exerts force on the feed material by pushing it against the stationary plate. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.

Moveable or Swing Jaw Plate. The job of the moveable or swing jaw plate is to take the material that has been fed into it and press it against the fixed jaw plate, thereby crushing it. This is a compression action that requires a lot of force by the swing jaw plate to accomplish. Most jaw crushers are V-shaped.
