What are the current international standards of MTBF for kilns and mills
admin
There is a difference between mean time between failures and mean time between stops. Best practice for kiln MTBF in the cement industry is in excess of 750 hours, while MTBS is somewhat shorter. The problem with MTBF is that it is easier to massage the data and cheat because some stops are planned and therefore do not count. In that situation it is easy to bring forward a planned stop when you have an unexpected unplanned stop.

Is there any international benchmark regarding maintenance cost for a cement plant? What is a reasonable figure per tonne of cement or tonne of clinker? I know it depends on the age of plant, technology, the country, etc.

As you say there is no true reply to your question, however if you can reduce your total maintenance costs below US$5 per tonne then you will be among the best factories in the world!
