Abstract: Process for monitoring a pelletizing plant for fine-grained ores, in which the humidity content of the green pellets is adjusted by adding water with consideration of the humidity content of the fine ores and humidified ores, together with optional additives, are hardened on a travelling grate by a heat treatment, characterized in that the green pellets are charged onto the travelling grate and the permeability and optionally also the humidity of the pellet layer is measured, in that the measured values for the permeability and the measured values or the preselected value for the humdity of the green pellets are supplied to a process calculator for monitoring the process on the basis of parameters, such as the process gas temperature, the process gas pressure, the travelling speed of the travelling grate and the amount of charge supplied, preadjusted or defined at the begin of the process, and in that the process is monitored by comparing the value for the position of the sintering point on the travelling gra
