Performing a Cement Plant Operations Audit
Operations audit is the first step in conducting a general and objective assessment of a production/operations area. It is called by many other names, such as diagnostic review, general survey, operations exam, etc. It can be done as a stand-alone project, but is often part of a larger project, such as reducing costs or improving productivity.

Cement clinker - Wikipedia
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
