Optimal Design On Chamber Of Cone Crusher

Cone crusher is the main equipment of rock material crushing and it is widely used in metallurgical and mining industry. However,home cone crusher have not been developed since they were imitated successfully, and those technology levels basically rested on the first and second generation of foreign advanced product. Furthermore, domestic cone crusher is designing conservatively, manipulating inconveniently and heavy,low efficiency,power wasting and poor product quality.Encircling in order to improve working performance of the cone crusher, this paper will be positioned to study chamber optimal design of the cone crusher.Based on research basic results of Evertsson who is a scholar of Chalmers University of Technology, the paper was expanded from various eyes of crusher working mechanism and working performance, and several researchs were finished, including crushing mechanism, crusher capacity model, chamber design model, crushing product grain size distribution model and multi-objective optimization model and so on. The paper mainly included these research contents as follows:(1)The significance of chamber optimization design and improvement working performance of cone crushers was discussed in this paper after analysing home and overseas situations of study on cone crusher.(2)Kinetic characteristic of spreading and granular materials in crushing chamber was deeper studied and three different forms of particles flowing state,that is sliding, free-falling, sliding and free-falling state of coexistence were discussed in this paper. Moving track model of spreading and granular materials in crushing chamber was built up by analysing the effect of moving state to working performance of cone crusher.The delamination broken point of cone crusher was put forward in this paper.These researchs were laid a foundation for delamination design and study on crushing chamber.(3)The calculation model of crushing product size distribution of rock based on the overall balance model was built up after analysing the effect of chamber to product size distribution of rock. A new formula calculating production capacity Q was put forward after taking into account fullly the effect of volume filling rateμi(α) at level section to production capacity.(4)For researching and developing of high-performance laminated cone crusher, multi-objective optimization model about production capacity Q,crushing product size distribution and chamber based on researchs of working mechanism and working performance was built up.Aimed at multi-objective optimization issue of PYB1200 spring cone crusher, calculation method on optimization issue was deeper studied.By using a random direction search algorithm of MATLAB programs to calculate multi-objective optimization issue,a optimized structure of the crushing chamber was mapped.(5)In order to further perfect the research on working mechanism and working performance of cone crusher,a analysis of the inadequacies and the objectives, methods and contents on further study were put forward in the end.Research results of this paper provide the basis for developing the cone crusher of new style,high efficiency,energy saving, environment protection and independent knowledge property right,optimization programs can be related to the commercialization of chamber design software development for reference.
