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.

1.2 The jaw crusher. Crushing is the first stage of size reduction of mined rocks. Primary crushers are heavy-duty machines, used to reduce the run-of-mine (ROM) ore down to a size suitable for easy handling. A line diagram of a double toggle jaw crusher and its main components is shown in figure 2. The jaws are set at an angle to each other.
A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...

Jaw Crusher is a basic sample preparation unit and is essential to address all primary size reduction requirements. Desired crushing takes place when fed particles experience stress and the compressive pressure exerted by the jaw blade toggling action exceeds its fracture stress. By this action the feed particles are crushed to smaller sizes.
