Do You Know the Existing Problems of Jaw Crusher in China?

At first, we talk about the history of the stone jaw crusher. Jaw crusher was invented by the United States EW Blake invention. Since the first Taiwan mandibles crusher since the advent, has been 140 Duonian history. In the process, its structure was perfect. Because mandibles crusher structure is simple, make easy, reliable and convenient operation and maintenance, so in metallurgy, mining, building material, chemical, coal etc widely used.

Domestic jaw crusher frame structure design is not reasonable examples have many, the reason is not in the actual stress to decorate crusher reinforcement. Dynamic jaw structure design also answer with dynamic force as the basis, the jaws in meet the requirements of the strength, stiffness and tried to reduce the mass. In addition, should strengthen the frame, dynamic finite element research, jaw frame, dynamic finite element optimization design to the jaws frame, dynamic jaw light quality and high reliability.

And every domestic manufacturers of mandibles crusher is very technical level one, the product of manufacturer of a few basic closer to the world advanced level, and most manufacturers of products and the world advanced level difference is bigger than others.

In addition, domestic jaw crusher of general prep above heavy machine with specifications of the crusher abroad. Reduce machine is one of the important topic heavy. Jaw crusher machine frame a large proportion of the quality of the whole machine (casting frame 50%, welding frame 30%). Foreign jaw crusher is welding jig, even move by welding structure and jaw.Jaw crusher welding frame is the development direction.

What’s more, it also to determine reasonable parameters, crushing cavity, crusher power balance can auto-balance of calculation for the optimization design. In a word, should adopt the modern design method of conventional design method instead of the original, and gradually make the homemade jaw crusher reached the world first-class level....
