A model design for the charging apparatus of a sintering machine has been studied to propose a method of adjusting model rules. In this method, dried are similar to the wet original raw mix in size distribution is used for model mix, and Floude number is taken into account in order to decide the operating conditions of the model sintering machine. This method has been checked by comparing size segregation in the bed between original sintering machine and 1/5 practical model, which has resulted in good accordance practically.
