With the rapid development of the economy in China, a large number of projects have sprung up, which need large quantities of high quality sand and aggregates. It has propelled the development of crushing industry, among which the high quality crushing and screening equipment is in increasing demand of the large-scale engineering construction industry. The production of aggregate resources is in urgent need of the research and development of large crushing equipment.

Jaw crusher and other screening devices can crush stones which are used in highway , high-speed railway, hydropower station, high-rise buildings, airport, municipal engineering and other industries. The sand and aggregate production line consists of large jaw crusher can produce finished aggregates with reasonable gradation and good grain shape. The elongated particles can be controlled within 5%, which is successfully used in high-speed railway, the Olympic projects, reservoirs, hydropower station and other national key projects.

Dingli Machinery has developed a series of crushers which take high efficiency, high yield, low energy consumption and strong environmental protection effect as the core with the conformation to the modern trend. Jaw crusher has not only increased the production capacity and efficiency, but also expanded the scope of its application. From limestone to basalt, from the production of stone to a variety of ores, it can provide a incomparable crushing performance in a variety of fine, medium fine and super fine crushing of materials. Jaw crusher is the most widely used crusher in mining industry, which has high crushing ratio, uniform product size, low operating cost, simple structure and convenient repair.

Jaw crusher can be divided into coarse and fine crushing, with the compressive strength of below 350 MPa. The 1200*1500 type jaw crusher produced by Dingli Machinery has deep crushing cavity and long stroke, which is suitable for the crushing of materials. When compared with similar products, it has greater production output. Especially for the design and production of large jaw crushers, the science and technology of Dingli jaw crusher has been in the leading level of domestic market. As one of the main products of Dingli Machinery, jaw crusher is mainly used for the first stage of crushing in the production line. It can be used alone or for the supporting devices of other crushing products.
