Abstract
To provide a tool for performance evaluation of aggregating occurrences afterwards-pertaining to the desulferized limestone´s calcination, we propose a threedimensional particle adhesive model repose on dynamic optimization of Monte Carlo. Based there on, we firstly develop a computer simulation on the formation mechanism of the microstructure of calcinated limestone. Then, sensitive observations and detailed analysis has been initiated by the dynamic changing laws on the process of the above-mentioned phenomenon. The results suggest that successive variation from the external dimensions and internal microstructure has been taken place in parallel with augmentation of the fractal dimensions range from 2.45 to 2.70 and a reverse trend towards the porosity range from 0.53 to 0.65. Moreover, this finding also makes evidence that the proposed model is well capitalized on revealing the discipline on the formation mechanism of the microstructure of calcinated limestone.
