Optimizing the operation of straightgrate ironore pellet
Mathematical models of straightgrate pellet induration processes have been developed and carefully validated by a number of workers over the past two decades. However, the subsequent exploitation of these models in process optimization is less clear, but obviously requires a sound understanding of how the key factors control the operation. In this article, we show how a thermokinetic model of ...

A dynamic mathematical model of the complete gratekiln
Induration drying and hardening of iron ore pellets is an energyintensive feed preparation step for both the blast furnace and direct reduction routes to iron. It is commonly carried out by a gratekiln process. A mathematical model of the process is described, in which mechanistic models of the grate furnace, kiln, and cooler are linked to enable simulation of the entire process.
