A dynamics model suitable for applying the system control theory to pulverizers has been developed. In this report, the dynamics model is discussed through the following order : (1) describing pulverizers, in which particle size distributions have the non-Gaussian properties, with the state space form as stochastic systems, (2) reducing the order of the state space by the proposed parameterizing method using the moments of the particle size distributions, (3) deriving the modeling algorithms for the proposed method, and (4) validations of the model through analysis on a commercial plant and dynamics response data of a pilot plant.
