摘要
探讨了分形理论在含钾页岩粉碎过程中应用的可行性,论证了借助分形维数的变化定量分析粉碎过程中粒度分布变化的准确性。结果表明:随着能量的积累,产品的粒度分布分维数先增加后降低,由2.099先增加至2.134,然后下降至2.058。分维数变化与均一度变化的线性相关系数为0.998,与均一度、均匀性系数相比,分维数表征效果更优。
This work investigated the feasibility of applying fractal theory in the grinding for quantitative analysis of particle size distribution via the change of fractal dimension.The results showed that fractal dimension of particle size distribution was reduced to 2.058 after an increase in the earlier stage from 2.099 to 2.134.Linear correlation coefficient between fractal dimension and regularity was 0.998.Compared with regularity and uniformity coefficient,fractal dimension revealed a more effective representation.
