The purpose of this study is to develop technology of the particle size adjustment of dry recovered powder of MOX pellets. Pulverization and classification experiments were conducted using simulated pellets obtained from materials having similar hardness and different density (specific gravity). We report that the results of pulverization and classification experiments in which experimental parameters were the clearance of the centrifugal classifier affecting the classification performance of the collision plate type jet mill.
