Simplified mathematical models have been developed for the steady-state operations of single-pass continuous balling drums and disks. Random coalescence between agglomerates is considered to be the mechanism of pellet growth. Analytical expressions for the moments of the green pellet size distributions have been derived for continuous balling drums; numerical methods are needed for balling disks. The effect of relevant factors, such as residence time, flow characteristics and water content of the feed, on the performance of these two balling devices has been determined. The results are generally in accordance with the plant data available at present.
