The jaw crusher is a kind of Stone crusher, also called Rock crusher. This series of Jaw crushers have many advantages which mainly used in breaking a variety of ore and the medium-size chunk of materials. The compression strength of the materials to be crushed is less than 320MPA. it can be divided into coarse crusher and fine crusher.
There are many models of jaw crushers in the world. However, the jaw crushers can be divided into a single elbow crusher and elbows crusher from the structure of the jaw crusher. Nearly half a century, many factories have made the modern technology, such as a variety of senior roller bearings, hydraulic technology, non-blocking type of crushing chamber and high-strength materials apply to the structural improvements of the jaw crusher, which has obtained satisfactory process.
To build a mining factory is to make a piece of earth area clean, which is beneficial to people living. As for mining ore exploring area, we are suggested that persist on green developing concept. More attention should be paid to safety production, at the same time, clean production and environmental protection are also critical. Therefore, we should make every effort to improve recycling rate, reduce the amount of waste emission, bring down production energy consumption and increase operation benefits.
It is pointed that it is necessary to create a sustainable economy so as to develop a resources saving and environmental friendly society. That persist on  developing while give priority to saving energy is based on the phrases of resources exploring, production consumption, waste recycling and customers consumption, so that build a reasonable resources recycling system. Most importantly, the comprehensive utilization of resources should also be intensified.
It is not an easy thing to maintain a mining exploring factory. The relevant experts introduced that the present built main ore dressing projects,  many of which adopt PL full-automatic control system, are international advanced as for the stone broken equipment, ore grinding equipment and flotation equipment so that it greatly improves ore disposal capability and useful ore recycling ability. In general, they invest 10 million RMB in ore processing line to build large capacity, high security and more standard residue storage and waste water treatment facilities. It doubtlessly provides reliable support for steady eco-environment in mining production.
In future, mining machinery tend to be more digital, more intelligent, more ecological and more humanized.  We paid great pains and considered issues both efficiency and environment protection based on the scientific energy saving theme. Only realize the importance of mining production and good service can we are expected to speed up mining construction progress.
