Drive components of a rotary kiln are:
Main drive motor
auxiliary diesel or motor
pinion (gear & bearings)
main (bull) gear
This could also be expanded to:
kiln riding rings
Evaluation will include looking at wear patterns, misalignments, and general tolerances in the system. Evaluating foundations and grouting and general mechanical operability. It is important to identify a problem, to prevent a failures. Having a third party look at a plant can see problems that may be overlooked by the day to day personnel.
