However, the domestic rock cone crusher hasn’t developed too much since the successful imitation in twentieth century.
The technique is staying in the first and second generation level of foreign countries.
Besides, the domestic cone crushers are too conservative, heavy with low efficiency, high energy consumption and low crushing quality.
Therefore, hard working should be done to improve the performance of China cone crusher.
.
Encircling in order to improve working performance of the cone crusher, and based on research basic results of Evertsson who is a scholar of Chalmers University of Technology, the research 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:
The significance of chamber optimization design and improvement working performance of cone crushers was discussed after analyzing home and overseas situations of study on cone crusher.
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 analyzing the effect of moving state to working performance of cone crusher.
The calculation model of crushing product size distribution of rock based on the overall balance model was built up after analyzing the effect of chamber to product size distribution of rock.
A new formula calculating production capacity Q was put forward after taking into account fully the effect of volume filling rate at level section to production capacity.
For researching and developing of high-performance laminated cone crusher, multi-objective optimization model about production capacity, crushing product size distribution and chamber based on researches of working mechanism and working performance was built up.
In order to further improve the working principles and performance of cone crusher, according to its shortcomings, more research aims, methods and content should be done.
The result of the researches can be used to research and develop automated, highly efficient, energy-saving and environmental friendly modern cone crushers.
