The Barring drive, also known as Inching drive, Sunday-drive or auxiliary- drive, is an important component of any mill installation. It is used for maintenance and inspection purposes, as well as an emergency auxiliary drive to keep the mill rotating when the main motor fails and it is required for the mill to rotate at certain intervals.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

The typical mechanical inching drive motor speed is around 1500 to 1800 RPM while the mill inching speed is in the order of 0.1 to 0.15 RPM. Thus, the gear reduction ratio between the inching drive motor and the mill is roughly 12,000 to 1. What this means is that the inching drive motor must turn 12,000 times to be able to turn the mill once.
