Underground Transport Compact Gear Units for Belt Conveyor Systems

摘要

As a line of units that take up little space, the MC industrial gear unit series from SEW-Eurodrive is suitable for mixers, cranes and belt conveyors. As fully assembled unit with motor and coupling, it is used below ground for driving belt conveyors in a South African chrome mine. Besides the energy efficiency of the drives, the customer placed great value on monitoring the condition of the drives. Consequently, SEW uses diagnostic units to reliably monitor rolling bearings and gearings, as well as oil aging. Chromium is used in various applications in which its stability plays an important role. The metal, chromium, is almost exclusively mined as chromite (iron magnesium chromium oxide) through open-pit mining or at shallow depths. Metallic chrome is obtained by reducing the ore with aluminum or silicon. The largest quantities of chromite are extracted in South Africa - 36 per cent of the world's requirement in 2006, according to the International Chromium Development Association.
