Mill scale is a very tempting industrial waste because of its richness in iron (about 72%), which makes it suitable for recycling either in sinter or pellet plants. Although considered a “green waste” as it does not generally contain any inflammable, toxic, or corrosive material, its recovery from underneath the rolling line poses demanding challenges due to high temperatures, fugitive dust, and material spillage. The Magaldi Superbelt® conveyor has proven to be key to the conversion of mill scales from waste to valuable products. The Superbelt® conveyor features partially overlapping steel pans securely bolted on a patented steel double-wire mesh system. The belt damage-tolerant design is based on a multi-link concept: the mesh provides redundancy, little to no maintenance, and trouble-free continuous operation. Even in case the mesh gets severely damaged, the conveyor will keep running without sudden failures until the scheduled maintenance. With the Superbelt® conveyor, high temperatures issues are solved thanks to the patented method of connecting the pans to the mesh belt, which leaves all components free to thermally expand in any direction without permanent deformation. As a result, the conveyor is able to withstand temperatures of up to 1,100°C.
