The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.
