Basically you are using Sturtevant Separator o-sepa N-5000 for Mill Capacity 240 T.
Strurtevant from USA to Indonesia to malaysia to Japan to Australia has been repalacing them..
Everybody is doing so. Why do you ask us? Why do you not question your Supplier?
For your information here are some statics on their Separator Replacements:
1990 Japan - 9 , Australia - 2
1992 Japan - 2
1991 Japan - 4
1987 - Tiawan 6
Why are your Owners not bold enough to question the Supplier? or ask for preventive maintenance.
It seems that you are just going about trying to waste our time. take my suggestion - if you waste this same amount of time with Sturtevant Separator you will get more knowledge.

See if an undergraduate study visit to a real cement kiln is available. The impression left by that huge flame swirling up the middle of the kiln is indelible.

What do you want to know about? Manufacturing process? Equipment used? Distribution? Please provide a little more detail so that we can help you out here.
Since you mentioned "especially machines", I would suggest you google for conveyors, dry powder handling equipment, crushers, and kilns, since these are the most basic equipment used in cement manufacture.
