Inching drives – one way to improve mill safety

2022 4 11   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.

Coal Mill Safety

VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is 100% capable of making a system that conforms to these and is therefore safe. However, this is not the case.
