At this era, the proportion of the concrete is larger in the construction industry development; concrete was involved in 90 percent of the buildings. We can say that the concrete is indispensable to the building. Concrete is made of cement, sand and stone. Stone and cement are the major strength materials in the concrete, so we can recognize the importance of stones in the concrete.

The crusher is widely used in many sectors of mining, smelting, building material, highway, railway, water conservancy and chemical industry. The commonly used gravel machines are jaw crusher, crusher, winnowing mill, hammer crusher, impact crusher, roll crusher, compound crusher and so on. The jaw crusher (jaw crusher), has a big crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, low operating cost. Side of the PF-I series of impact crusher can process 100 to 500 mm long and the following materials, the compressive strength of up to 350 MPa, with broken than large, the material was broken cube particles, etc.; PF-II series impact crusher machine, which is suitable for hard materials in the crushing, such as cement plant limestone crushing capacity,and so on.

The crushing chamber is the most important institutions for the crusher,its crusher cavity shape influence the performance of the crusher cavity greatly, especially the shape of the crushing machine. Kariba off crusher is divided into standard, medium, fine and superfine these four kinds of cavity shape. Order to the materials and broken product particle size accumulated content to 80% by fine-grained is showed as D and d, crushing the ratio is D and d h . For standard and medium crushing chamber h = 4 to 6; h = 2 to 4 for fine and superfine crushing. Various specifications crusher is equipped with a cavity (liner), as to the maximum feed size and minimum discharge mouth wide,we don not enumerate them here. When designing, we should listen to the users’ views and experiences who are the long-term users of the crusher on the problems ,should solve the problem addressed in the design, so that the new design of the crusher can improved,innovated based on the original development, let us first takethe 2200 bottom of the single-cylinder Hydraulic Cone Crusher as example,and calculate the strength of the computer frame.
