The jaw crusher is invented by American EW Blake. Since the advent of the first jaw crusher, it has been 140 years of history. In this process, the structure has been constantly improved. Jaw crusher structure is simple, easy to manufacture, with reliable work, easy maintenance, and so widely used in metallurgy, mining, building materials, chemicals, coal and other industries. Domestic manufacturers jaw crusher technical level is poor, there are a small number of manufacturers of products is close to the world advanced level, while most of the manufacturers of the products have larger gap in the world advanced level with the developed countries.
In addition, we should strengthen the finite element research on rack and moving jaw rack to achieve the rack quality has a high degree of reliability. In addition, it is also reasonable to determine the parameters of the crusher, crushing chamber, and crusher power balance to optimize the design. In short, modern design methods should be used instead of the conventional design method and gradually to make domestic jaw crusher reach world-class level.
The machine weight of domestic jaw crusher is generally higher than that of foreign specifications. Alleviate the machine weight is also an important issue. There are many examples of unreasonable structure design of domestic jaw crusher; the reason is not arrange the crusher according to actual force ribs. Moving jaw structure design should base on the moving jaw force to meet the strength and stiffness requirements of conditions to minimize the quality.
