Blake Burgeth, Intermediate drive technology as a cost-saving solution for belt conveyor upgrades, in Naj Aziz and Bob Kininmonth (eds.), Proceedings of the 2019 Coal Operators Conference, Mining Engineering, University of Wollongong, 18-20 February 2019, 133-137.


The demand on belt conveyors continues to increase. Availability and reliability are key factors for increased productivity. Linear booster drives for mining conveyors were initially used in the US in the 1980-90’s with marginal success. The primary issue of this technology was controlling and transferring the power to the belt. Voith has successfully applied linear booster drives to over 300 installations worldwide. The Voith TurboBelt “TT Linear Booster Drive”, is optimized in a complex engineering process to meet the customers’ targets. Linear booster drives can save 25% or more on both Capex and Opex costs. This paper highlights the advantages of the TT are Drive concept, the potential applications that can benefit from this type of conveyor design, and cover examples of this technology. The TT Drive solution significantly reduces the belt tensions, allowing the use of lower rated and lower cost belts. This can benefit new installations as well as extend the life and/or upgrade the capacity for existing conveyor installations.
