Abstract/Summary A new kinetic model for diaspore digestion process has been proposed in the view of fractals. Considering characteristics of the natural diaspore particles, this paper introduces two fractal parameters, reactive fractal dimension, DR, and particle size distribution (PSD) fractal dimension, DpsD, to describe the irregular shape and rough surface, and the ruleless particle size distribution, respectively. A piecewise volume cumulative distribution function with PSD fractal dimension has been developed to express the PSD of natural particles varying with digsting time. Combining the piecewise volume cumulative distribution function, the new model, PSD+RC+F model, could express the diaspore digestion process well, by carrying out numerical analysis.
