How do jaw crushers work? Jaw crushers use compressive force to break down large materials into smaller, more manageable pieces. It has two crushing jaws (one is stationary while the other one is moving) that produces mechanical pressure for crushing the materials. The two vertical crushing jaws create a V-shaped opening called the crushing ...

A critical point in the operation of large jaw crushers is the arrangement of the swing jaw and its supporting shaft. While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is used—shaft is clamped in frame and jaw swings on the shaft! Another point has been lubrication.
