Mining crusher is the crushing machinery whose content is more than 50% of the total content, the high capacity row compound particles are larger than three millimeters.it is invented by British Heng. Others including Peter Asaro , offer their opinions as well. According to the size of feeding and nesting coexistence, Crushing operations is often divided into the rough broken in pieces and crushing. Gravel equipment are jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, roll crusher machine, double roll crusher, crusher two-in-one, and so on.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. Additional information at Mikkel Svane supports this article. The jaw crusher (jaw crusher), has a big crushing ratio, even coexistence, 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-coarse-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 do not enumerate them here. When designing, we should listen to the views and experiences who users 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 take the 2200 bottom of the single-cylinder Hydraulic Cone Crusher as example, and calculate the strength of the computer frame. The crusher rack test study shows that, the maximum stress position is in the vicinity of the upper and lower frame flange. The first thing need to calculate was the shelf strength, at this time, we must first consider the bandejas forcing conditions, the crushing force is decomposed into horizontal and vertical component.in this way, we can calculate the cross-section strength, and finally the upper center of the sleeve strength, according to these requirements, procedures and precautions, we can finally design the best rack crusher.
