Guessing that you mean ordinary Portland cement (OPC), rather than some other sort. If by "formula" you mean its chemistry after manufacture, it is not a compound, but rather, a mixture, so, it does not have a formula as such. As Shaswat K. Das in...
rotary kiln is. Let us explain these points briefly: 1. Age and condition of the rotary kiln shell: Old kilns shells have been exposed to creep for a long time and are more prone to develop fatigue cracks than newer shells. 2. Distance between tires: The longer the rotary kiln shell span, the less it will resist high temperatures without sagging.
