Voith GmbH, Heidenheim/Germany, has installed a TT Drive on the H2 belt conveyor in the RAG´s Prosper-Haniel coal mine in Bottrop/Germany without interrupting operation and achieved a comprehensive solution with the subsequent installation of another TT Drive that resulted in sustained cost reduction for the mining company.
With the installation of the first TT Drive, Voith made it possible for the Prosper-Haniel mine to carry on using a heavily damaged steel cord belt (ST5000) until the next scheduled downtime and thus prevented an unplanned shutdown and corresponding production loss. During the next downtime, Voith installed a second TT Drive in the H2 belt conveyor. This allowed for a further reduction in belt tension forces and Prosper-Haniel has since then been able to operate the belt conveyor with a cost-saving textile belt (PVG2000/1). The H2 belt conveyor transports the mined coal over 1,270 m with a lift of 186 m vertical. Its operating speed amounts to 3.2 m/s with a capacity of 2,000 t/h.
The Voith TurboBelt TT Linear Booster Drive is a high-performance secondary drive (Figure 1) for belt conveyors. It extends the use of belts in existing systems and increases their available power. In new belt conveyor systems, it reduces the requirements on belt quality, leading to considerable cost savings.
