In the mining industry today there is a growing trend and requirement to convey higher capacities of material at tens of thousands of tonnes per hour over longer distances; this tendency demands higher drive power of several Megawatts per drive. The issue however is finding motors and gearboxes that have power levels higher than 2 MW that can meet this demand.
Striving to meet market demands, Sandvik Mining Systems is in the design phase to develop belt conveyor systems with gearless drives for belt conveyors. In place of the gearbox you are presented with an electric induction motor that couples with the drive pulley directly, this set up enables the conveyor to operate both efficiently and effectively. The objective is to offer higher power levels for single drives and provide significant savings in operational costs of mines, and in addition, just as importantly, to provide a solution that is more environmentally sustainable.
