Internal System and Durability Design of a Crusher

Crusher is mainly used for mixing, kneading and crushing materials. Besides, it also makes materials form radial flow. Therefore, the main resistance of crusher mainly comes from the distorting effect that materials put on it. Because multistage mixing and kneading units are concatenated into crusher and units respectively consumes a certain amount of power, for this reason, from the input end to the output end of crusher, the distortion that crusher endures stepwise alter.

As for a horizontally installed crusher, there will be radial bending stress in it. The radial bending stress produced by gravity effect is alternating stress which is always equal in size and opposite in direction. Because the load condition of a crusher is relatively complicated, it is difficult to use a unified calculation method to respectively and accurately calculate the various changing loads inside the crusher under the influence of each mixing design conditions (including different fluid properties, the shape, size and position of lining plate, the structure of mixing equipment, mixing rotation and process operating conditions and so on).

Hongxing Machinery thinks that the durability structure design is an effective method to build a crusher and it also puts forward a crusher design method to share the performance of crushers. This method gets the functional decomposition diagrams of crusher by disassembling its functions, and it realizes the mapping from function structure diagram to crusher performance by introducing the heuristic performance classification rules and through the matrix qualitative analysis of the crusher performance to classify the performance and determine the universal and general functional crusher as a platform of crusher.
