Does anyone have any experience they would like to share with regards to the expected Iron levels on the Cyclo BBB4 speed reducers?
We are a new mining operation and have 5 of these units driving conveyor head pulleys. The first oil samples all came back with high iron counts (spectro analysis) and also high magnetic iron counts. All are over 120 ppm. Is this normal for these units?
**The Commissioning team mistakenly put a Mobil Synthetic gear oil in these 5 reducers. Sumitomo told me specifically DO NOT USE. They have seen failures with the reformulated Mobil SHC gear oils and therefore they are not approved for use.
I caught this screw up early but all reducers ran with the wrong oil for approximately 1 month.
So now on our first oil sample I am seeing high levels of iron in each of these 5 units so I am being very cautious. I am however concerned when I see these levels in other gearboxes.
Any input would be appreciated.
