As cement producers have different requirements for drives in vertical roller mills, the latest developments in the area of drive train technology offer a wide range of options. Especially in the case of higher mill outputs, cement producers nowadays frequently favour drive systems with multiple motors and gearboxes with milling force decoupling.
Renk AG, Augsburg/Germany as a leading gearbox manufacturer and Loesche GmbH, Duesseldorf/Germany as a provider of vertical roller mills (VRM) will together market the drive concept COPE for vertical roller mills exclusively in future, allowing them to develop this further in line with requirements. The agreement is valid for the next 5 years.
The COPE gearbox is primarily available for mill outputs between 4000 and 12 000 kW and represents a highly redundant innovative drive system for large and very large vertical mills, offering up to 8 motors at the motor end. As this power train retains the normal dimensions, the system is also suitable for retrofit gearboxes in existing mills.
