Besides being an important item for the machine’s performance, the jaw crusher’s jaws are responsible for front frame and swing jaw protection. Wear generally causes loss in production due to increased crushing angle, loss of tooth profile, reduction of the CSS to compensate the possible lamellar effect, etc.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher. Measuring Discharge Opening: Measure distance at bottom of jaws at the point of the crushing cycle when the bottom of jaws is closest together.
