The rates of the volume breakage and surface breakage of lump coke and the particle size distribution of the resultant products were investigated using a shatter tester and a drum tester. It was found that the change in the probability of the volume breakage of coke could be expressed by the Weibull function and that the surface breakage rate of coke was basically proportional to the weight of the particles. Based on the experimental results and applying the concept of the theory of comminution kinetics, the size degradation process of coke was analyzed. It was found that the size degradation process of coke could be described by the above two mechanisms and the effect of the volume breakage on the apparent surface breakage rate and that parameters of the volume breakage and the intrinsic surface breakage could be estimated from data on the size degradation behavior.
