  • How Does a Jaw Crusher Work Jaw Crusher Kemper

    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. The rock remains in the jaws until it is small enough to
