In a continuous balling process, which may be the formation of green balls from iron ore, water and a binder in a balling drum as a stage in the pelletizing of iron ore, which includes a balling circuit in which undersized balls are recycled directly together with further raw material, the phenomenon known as surging is reduced by a method which involves including in the process a stage modifying the fundamental direct relationship between discharged undersize balls and those recharged, this unmodified direct relationship being the recurrence of the discharged balls identically as recharged balls after a constant time interval. |
