N2 - Bulk materials which are transported with continuous conveyors, partly have a high energy content,depending on the specified mass flow and the conveying velocity. At discharge points to storageareas or at transfer points from one conveyor to another, the energy content often increases due tothe elevation of the discharge conveyor. It is possible to recover a large part of the energy due to themass flow (conveying velocity) and the drop height of the bulk material at these points. A so-called"Solid State Material Driven Turbine" has been developed at the "Chair of Mining Engineering andMineral Economics - Conveying Technology and Design Methods" at the MontanuniversitätLeoben / Austria , which allows recovery of this energy. This energy can be transferred directly tothe conveying system or via a generator to the electric circuit. In addition to energy recovery, thistechnology offers further benefits, which could be even more interesting than the actual energyrecovery. This paper introduces this new technology and focuses on additional benefits like wearreduction, avoiding particle size segregation, soft loading effects etc. Turbine prototypes, wear tests,simulation examples and economic considerations are shown.
