- How Crushing Takes Place In A Jaw Crusher
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.

Jaw Crushers. In compression crushing, jaw crushers tend to be more of a blunt instrument compared to cone crushers, which is why they're often used in the primary rock crushing circuit stage. Jaw crushers are also known as "rock breakers" and are used to break up larger, harder materials into more manageable pieces.

Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.

JAW CRUSHER is a basic sample preparation unit and is essential to address all primary size reduction requirements. Desired crushing takes place when feed 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.
