Grate process is an important step in grate-kiln pellet production. However, as a relatively closed system, the process on grate is inaccessible to direct detection, therefore, it is hard to control. As a result, mathematical models of temperature distribution, moisture distribution and oxidation degree distribution in pellet bed, with good …

A straight grate system emerged in the industry soon after the shaft furnaces. It is essentially a modification of the sintering process. The green balls are fed onto the grate continuously to give a bed depth of around 300 mm to 400 mm and are dried in the first few wind boxes by updraft air recuperated from the firing zone, followed by ...

Basically a straight grate induration furnace consists of three different zones, i.e. a drying zone, a firing zone and a cooling zone, and their purpose is to upgrade crude iron ore to the final product of iron ore pellet. As an initial step of the project, the mass and energy flows within a straight grate induration furnace have been analysed.
