A new gearbox generation for vertical roller mills

摘要

Drive trains of vertical roller mills are usually equipped with heavy duty gearboxes with a horizontal input shaft and a vertical output shaft. Increasing mill sizes bring the existing gearbox concepts to their limits, however. This, and the demand for higher reliability and lower costs, has forced gearbox manufactures to develop new gearbox concepts. In this article, an innovative new gearbox concept that meets all the demands of the latest mill generation is presented.
