Belt conveyor Ecobelt® DRI

The Magaldi Ecobelt® DRI is the ideal and reliable conveyor for handling very hot and reactive bulk materials, like Direct Reduced Iron (DRI) produced by rotating hearth furnaces (RHF) before further processing stages. DRI is produced by passing hot reducing gases over iron ore, which is usually in the form of pellets. Although the process is conducted at high temperatures, the pellets retain their original shape, but are considerably lighter owing to the removal of oxygen from the ore. The pellets have a hugely porous structure, which makes the material extremely reactive and prone to re-oxidation on contact with air. Therefore, 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 Ecobelt® DRI key component is the Magaldi Superbelt® , the ideal steel belt to convey difficult materials in industries where high dependability is essential, that overcomes the frequent problems encountered by conventional conveyors, such as chain conveyors. Wear is negligible, since material is slowly conveyed with no relative motion against steel parts.
