What Are The National Standards For The Design Of Jaw Crusher

Last Update:2020-05-08 20:14:43

The jaw crusher has a long history in the crushing industry. With the continuous innovation of crusher technology, the national standard of jaw crusher is also constantly updated, and its types and specifications are more and more. The specification of jaw crusher is mainly different with the different needs of customers. Because of the different design output of different production lines, the specifications of the jaw crusher equipped in the production line are different.

In our country, there is no exact document or policy to stipulate the standard of jaw crusher. Different manufacturers have different core technologies of crushers, and their R & D capabilities are also different. The design standard of jaw crusher is based on the properties of crushed materials, very large handling capacity per unit time, service life, failure probability and other aspects. If a kind of jaw crusher has a very good discharge particle type, the handling capacity per unit time is very large in similar equipment, the failure rate is low, and the service life is long, then this type of jaw crusher will become the industry standard.

There is a great difference in the technical level of crusher between domestic manufacturers of jaw crusher. The products of a few manufacturers are basically close to the world's advanced level, while the products of most manufacturers are far behind the world's advanced level. Foreign jaw crushers are all welding frames, and even moving jaw also adopts welding structure. The development direction of jaw crusher is to adopt welding frame. There are many unreasonable cases of the frame structure design of the jaw crusher in China. The reason is that the reinforcement is not arranged according to the actual stress of the crusher.

With the continuous improvement of the technical level, the design standard of the jaw crusher is constantly changing, and its changing trend is to develop in the direction of larger output, longer life, more perfect grain type and wider application range. In China, the development of E-crusher is relatively short, starting late, and the overall technical level lags behind the international level. Relevant R & D personnel still need to make continuous efforts to explore the core technology of crusher and make up for the gaps in relevant fields in China. At the same time, it also needs the corresponding financial support from the state.
