In dual pinion systems, torque and load sharing between motors is very accurate, improving the lifetime of the pinions. The mill drive controller also provides service operating modes such as creeping and positioning, so the drives do not need additional equipment for maintenance purposes.

the cause for failure. The study concludes that the failure is due to the compromise made in raw material composition by the manufacturer, which is evident by the presence of high manganese content and non-existence of nickel and molybdenum. This resulted in high core hardness (458 HV) leading to premature failure of the pinion. D. Lewicki et.al

The requirements for the mechanical devices and the power grid have become more demanding. Controlled soft starting and operation, especially in dual pinion mills, as well as the protection of the equipment has gained importance. The selection of the drive solution for the mill therefore becomes more critical.
