ABSTRACT:
A method for controlling an iron ore pelletizing and pellet processing operation by evaluating the results of the on-stream analysis of the apparent specific gravity or apparent density distributions of the dry and fired pellet samples which permits the operator of the process to determine if any changes in the process control factors are required in order to impart into the fired pellets an apparent specific gravity or apparent density distribution optimized therefor as the fired pellets are used as a blast furnace charge composition. The method includes the use of an apparent specific gravity measuring step wherein a pellet process stream is periodically sampled and the pellet samples are presented in sequence to a weight measurement unit capable of producing an electric signal proportional to the weight of each sample, from which it proceeds into a volume measurement unit photoelectrically responsive thereto to produce an electric signal proportional to the volume of the sample. A computer is provided in response to the electric signals to compute the apparent specific gravity of each of the samples. This permits a rapid and accurate record of sample analysis to be maintained for the effective control of the process factors.
