Cement Mill Barring Drive

Project Scope

Reaching out at the last minute before a planned maintenance shutdown period, Ingenia’s client required an improved barring drive clutch operation design – and quickly. Originally designed to disengage the barring drive when the cement mill main drive is running, the client needed to change the way the clutch was operating, which required the fabrication of new clutch parts with a different profile and an improved clutch operating system.


Not only was a fast turnaround needed for the job, but a complex design was needed to meet the client’s needs and improve the operation of the cement mill barring drive. After completing the initial design, Ingenia carried out a risk assessment, which identified that additional controls and interlocks were required to ensure that the changed functionality of the barring drive clutch mechanism would meet the AS4024 Safety of Machinery requirements.


After being designed by Ingenia and fabricated by a third party contractor, the project was completed within a short timeframe, allowing for installation and commissioning during the planned maintenance shutdown.

Positive feedback from Ingenia’s client advised that expectations had been met and exceeded yet again.
