MINAS-RIO BLAST FURNACE PELLET FEED INTRODUCTION

•With Chinese sinter plants feeding almost coarse sinter fines (some containing 50% pisolite ores), the following effects are observed: Low particle density, high fractional moisture and high bed voidage cause severe bed shrinkage and an “over” permeable bed The above leads to low productivity and a fragile sinter cake (low sinter ...
