Jaw Crusher is the most extensively used crushing machinery, and its first appearance was in 1870. Jaw crusher brought rock crushing to a mechanical era from handwork era. In the processing of iron ore, crushing is a very important step. Jaw Crusher is with advantages of simple structure, easy to manufacture and maintain, reliable working performance, less volume and height, and the history of 140 years in iron ore crushing, so it is widely used in metallurgy, mining, building materials, chemicals, coal and other industries. Long-term industrial production practice and deep development continuously improved the structure and work performance (operating parameters and structure parameters) of jaw crusher to a perfect level.

Today, Jaw Crusher has become the very sophisticated coarse crushing machine and general crushing machine of rock and mineral material. Although in nearly 20 years, small and medium mines, particularly medium and small sized iron ore mines use Jaw Crusher for fine crushing, but the results were not as good as expected. Anyway, jaw crusher is still ideal coarse crusher and general crusher.

At present, the Jaw Crusher is widely used in two forms: simple pendulum and complex pendulum. The simple pendulum Jaw Crusher was widely used in large mines in the past, but now Jaw Crusher with compound pendulum is most welcomed by many mines.
