The Magaldi Ecobelt® DRI is the ideal and reliable conveyor for handling very hot and reactive bulk materials, like Direct Reduced Iron (DRI) produced from rotating hearth furnaces (RHF) before further processing stages.
Since the material is extremely reactive and prone to re-oxidation on contact with air, the DRI handling process demands an inert atmosphere inside the conveyor to avoid the material oxidation.
Downstream of the direct reduction process, a further stage may consist of briquetting or smelting hot DRI pellets. In the former case the Magaldi Ecobelt® DRI has the function to cool down the DRI pellets, since the working temperature of the briquetting machine is generally in the range 500÷700 °C. In the latter case the higher the DRI pellet temperature, the higher the energy saving from electric arc furnaces (EAF) to smelt the DRI pellets.
The Magaldi Ecobelt® DRI key component is the Magaldi Superbelt®, able to withstand high temperatures and chemical attacks, designed completely enclosed in a steel casing to prevent dust dispersion to the environment. The Superbelt® damage-tolerant design eliminates any risk of sudden failures, otherwise always present in the case of conveyors using chains. The inner walls of the steel casing are coated with a suitable insulation to prevent heat loss during the transportation. Nitrogen or other suitable gases can be injected into the Magaldi Ecobelt® DRI to make the inner atmosphere inert.
