Jaw  crusher crushing equipment belong to the earliest generation of  products, owing to heavy machinery and machine vibration, impact force  generated in the production of relatively large, and a reliable and  robust body of its impact is huge, jaw broken shell normally used before  the  whole cast, but casting a huge gap between the various factories, and  some relatively immature technology, produced by the shell invisible  injury, sand holes inside more, for the production of quality and safety  of potential problems, and now we are using steel welding process, Second-welding process more reliable cried the whole body, joined  us after welding hardening, machine vibration and other processes,  greatly to ensure the solidity of the body's overall stability and  welding mouth.
   From  the shell crusher manufacturing process is concerned, the same can also  be classified as other, to make a more detailed attribution. Here crusher shell is usually only. At  present, the domestic crushing equipment used in "armor" is nothing  more than the whole cast steel after welding or cutting made standard. Many  times we would be very concerned about its core power, specifications,  service life, but few customers and friends concerned about its housing  production process have much impact on the life of the crusher? Not difficult to imagine the two different levels of the production process, use is also not the same length. But  it is worth noting that it is, with the upgrading of deep-saving  concept and design of the production process, welding rack jaw crusher  prospects and applications can not be ignored. Damage  to certain parts of welded frame can be replaced with the same parts,  without replacing the whole, therefore, in order to create a  conservation-oriented society, not only the production process, our  responsibility and the concept is also an important driving force for  development.
