Drive selection for large Loesche vertical roller mills
M. Keyßner, T. Fahrland, Loesche GmbH, Duesseldorf, Germany
Rising demand from the cement industry for ever greater mill capacities is having implications for the drive systems that have been used up to now. With conventional drive solutions reaching their limits, the world’s leading gearbox manufacturers are developing new systems that can offer realistic alternatives for the higher-capacity mills that are now being ordered and delivered. This article looks at how Loesche undertook the evaluation of the best gearbox system for a new, high-capacity vertical roller mill, and explains the thinking behind the decisions made. After a summary of the most important functions of the drive for a vertical roller mill, its design and design limitations, there is a detailed comparison, using a real project, to select the best available drive system.
