ABSTRACT:
Water and particulate material are placed in the pelletizer and the pelletizer rotated. The size distribution of pellets at the output of the pelletizer is controlled by altering the amount of water, or particulate material injected into the pelletizer. The output of the pelletizer is screened into two or three discrete sized groups. The groups are periodically weighed and the ratios of their weight are compared to a predetermined standard or to the ratios of the weights of a previous set of groups. The amount of water injected into the system is altered responsively to an excess weight of either the smaller or the larger sized pellets.
