Abstract

In order to investigate the effect of ultra-fine smash on the separation results of Shenfu semi-coke, the impact crusher was used to explore the relation between the degree of dissociation and the particle size and ash content. Additionally, the operating parameters of separation device of impact crusher was analyzed by the orthogonal experiment method and then it was optimized. The result of particle size analysis and oil absorption measurement to the ultra-fine smash of semi-coke reveals that both the ash content and oil absorption decrease with the increase of particle size, which indicates that the minerals of semi-coke are enriched in the fine fraction and the surface area of semi-coke ratio is increased after the ultra-fine smash. The proportion of ash content is 5.81%, the d97 is 82.09 m and the productive rate is 22.67%, respectively, while keeping the air inlet half-open, the speed of crusher 2900 r/min and the speed of classifier 700 r/min. In conclusion, the experimental results reveal that the volume of air inlet, the speed of crusher and the speed of classifier take the dominant effect on the particle size and purification of Shenfu semi-coke, moreover, the impact crusher has an extra impact of separation while smashing the ultra-fine of the semi-coke.
