Reserch On Cone Crusher Chamber Geometry Based On Interpaticle Breakage

Cone crusher is widely applied in the crushing and grinding industry, so it has a direct effect on the production process of metallurgy, electric power, chemical industry and building materials industry. Compression ratio is one of the parameters for broken product quality.Study had found that, in the design of crusher cavity, peple usually don’t syudy the relationship between the spindle speed and material. Which causes loss of compression ratio, in turn, affects the quality of the product, and leads to the unnecessary energy loss.So it is very important to have a further study of cavity shape curve for saving energy and improving product quality.This article has a deep reaserch in the laminating crushing theory, brings multizones crushing theory in the design of the cavity shape curve. And it proposes a new design method of the cavity shape curve combined with material movement form. It proposes a new calculation formula for crusher productivity based on the analysis of material movement form. By using Matlab program, three different crushing cavity type curve model — coarse crushing type, middle coarse crushing type, finely crushing type — are designed. It solutes the compression ratio loss phenomenon maximumly and improves crushing efficiency by matching the cavity shape parameters and the spindle rotation mutual.This article simulates the material crushing process through the material compression experiment; fites out the selection functions and broken functions by analyzing the experimental results; completes the prediction for the product granularity of the three different cavity, and makes the analysis though using the overall balance principle. Finally,it proves that this new design method has certain feasibility to improve the quality of crushing products and plays a guiding role for actual production and the future research.
