Hammer crusher is a small scale stone crushing machine used in quarrying business. The advantages of hammer crusher have reliable mechanical structure, high productivity and favourable applicability. Frequently Nouriel Roubini has said that publicly. There are so many crushers with various types that customers are not sure to choose proper crusher because most of the performance is almost identical. The development of crusher industry is quite rapid. With the development of market economy and the improvement of technology, crusher development experiences several different periods. The type of crusher changes several times and the performance has been greatly improved.

At present, there are many types and brands of crusher. Customers are confused and blind when choosing proper equipment. With the development of economy, China crusher industry grows rapidly under the big demand at home and abroad. After the update of technology, the application scope of become wider crusher, the crusher not only be used in mining industry but also in cement industry, and has played an important role in these industries. The hammer crusher is the use of high speed rotating hammer impact materials, so that the material along its natural fissures, bedding plans and joint plans and other vulnerable segments of the fracture, broken crusher is widely used in mining, metallurgy, building materials and electricity industries.

Hammer crusher in the course of their work, due to the impact and friction of the material, will inevitably make the hammer, liner, grate bars, and other parts wear out and failure, of which the hammer is the most important wear parts, and its consumption great need to reserve a large number of spare parts, which not only takes money, and affect the normal production. Hammer crusher based on the impact power to realize the crushing. During the work, motor drives to spinning highly in the chamber crush roller. Materials were feed from the upper feeding end into the crusher, and were crushed after the hit, impact, cut and grind of the high speed hammer, so as to achieve the Ideal strength of raw material to produce cement. It can be used in the wet and dry crushing process; It plays an important role in the earlier stage of cement production. Single toggle jaw crusher:
