THE CIRCLE OF FLEXIBILITY CIRCULAR PELLETIZING .

Contrary to straightgrate systems where onehalf of the induration grate is returned empty to the charging station, the circulargrate design of a CPT plant means that the equipment utilization can be fully optimized. Not only can the required grate length for a given output be significantly reduced with CPT, energy costs are also reduced....

heat mass balance in in iron ore pellet induration furnace

Basically a straight grate induration furnace consists of three different zones, 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....

Siemens introduces Circular Pelletizing Technology ...

This solution is based on the wellproven travellinggrate pelletizing process, however, the circularly designed induration furnace greatly reduces the footprint of the pelletizing plant. Overall space requirements for CPT are approximately one half of those needed for a conventional pellet plant....

CONTRIBUTIONS TO THE TECHNOLOGY COMPARISON .

The gratekiln process, which has been inspired from furnaces designed in the cement industry, uses three distinct pieces of equipment to carry out the induration process: a preheat travelling grate, a rotary kiln, and an annular or straight cooler. Drying and preheating of the green pellets is accomplished on the preheat grate,...

Optimization of Firing Temperature for Hematite Pellets

cooling zones. The induration furnace consists of three main steps 1. Drying of green pellets (200 to 350°C) 2 Firing of the pellets at 1250 to 1320°C to sinter the mix 3. Cooling of the hot pellets to (900 to 80°C) before discharging them on to the conveyors. In the induration furnace corex gas is used as fuel for firing purpose....
