Implementation of an iron ore green pellet on-line size analyser at the QCMC pelletizing plant

摘要

This paper describes work into the design, implementation and performance of a 3D-image analysis system at the QCMC pelletizing plant. First, the measurement system is reviewed. Second, the ability of the system to achieve reliable, on-line results on a moving conveyor belt is presented and discussed. The problem of sepregation caused by disk classification is particularly addressed, as it hinders full size distribution estimation from the top layer. Finally, pelletizing disk controllability is investigated.
