Mining crushing machinery has been widely used in more and more industries. There are many kinds of crushing equipment used in the industry, and there are many kinds of classification methods. According to the working principle and structural characteristics, it is divided into: jaw crusher, cone crusher, roller crusher and impact crusher. In addition, there are special types of crushers.

Before liberation, my country could hardly produce any type of crushing equipment. After liberation, there was a crushing equipment manufacturing industry, which started from imitating old foreign crushers, and gradually developed to design and manufacture various crushing equipment by itself. By the 20th century A series of products have been formed in the 1960s. From the late 1970s to the early 1980s, due to the introduction of foreign advanced production technology and equipment, and after digestion and absorption, my country also began to produce some crushing equipment with international advanced level. At the same time, all kinds of traditional crushing equipment produced in China have also been transformed or updated in terms of structure and material, so that the performance of the equipment has been improved, and the specifications of seed crystals have been increased, forming a series of crushers for different purposes. It has basically met the needs of domestic industrial sectors such as mineral processing. However, compared with the foreign advanced level, there are still some gaps in equipment structure, variety specifications and technical performance. In recent years, with the further development of my country’s crushing equipment and the cooperation with foreign countries to produce advanced crushing equipment step down
