Exploiting the high temperature fluxion character of grate cooler clinker, the filling state during entire colling process can be determined. Then impact on the control model can be analyzed introducing by the fluctuating of the clinker's thinkness and diameter. a modeling method with three dimensions division is proposed. The Longbeige step-changing dichotomy is used to optimize the division time toward z direction. Then the mass balance and heat balance analysis for every cell derived from clinker's three dimentions division is presented. Finally, the clinker temperature field's unitary control model with deducing in x, y, z direction separately is constructed.
