KILN AUDIT
TYPICAL SCOPE of KILN AUDIT (measurement and correction carried out during normal kiln operation)
- Determine geometrical axis of support system in
- Horizontal plane
- Vertical plane
- Determine global inclination of kiln
- A simplified analysis of the shell deflection to determine local inclination angle of the facility in the support points.
- Determine skew of support roller in
- Horizontal plane
- Vertical plane
- Computation of direction of axial reaction forces acting on the kiln
- Determine detailed parameter as :
- Migration of tyre and resultant under ring clearances
- Spacing of support rollers
- Spacing angle of support rollers
- Height difference of roller shafts
- Diameter of ring (tyre) and rollers at 3 sections
- Determine axial position of Girth gear – Pinion, tyre – rollers
- Visual inspection of kiln condition, support system, shell, seals, thrust rollers, drive sections.
- Calculations, review of obtained parameters, determine the corrective settings for the support system; develop the corrective actions for the facility.
- Measurement of dynamic deflections of shaft (determine load variability, detection of so called hidden crank – located in the support area.
- Measurement of kiln shell profile along kiln length @ 2 meter
- Measurement of Girth gear wobbling (requires side machined face of GG free from dust / lubricant / foreign material)and & eccentric run of shell at girth gear portion
- Conduct a class explaining HKA findings including discussion on problem observed in kiln and reduction / elimination of root causes for trouble free operation.Foundation settlement (requires visible level marks on the foundations)
