The majority of problems associated with rotary kilns can be attributed to misalignment. As such, comprehensive hot kiln alignment ensures that rotary kilns are able to achieve maximum efficiency throughout their service lives and help users avoid unforeseen breakdowns.
MEASUREMENTS & ANALYSIS
The first stage of the hot kiln alignment process involves precise measuring and analysis of the actual rotary kiln deformations at the time of investigation. This is and automated process and done with the aid of state of the art measuring equipment including electronic theodolites and complex computer programs.
OUTCOMES
The analysis not only presents results but also provides data and guidelines for aligning and supervising machine repairs.
Actual rotary kiln alignment status
Condition of the tyres and trunnion rollers including tyre chairs and tyre stops
Tyre and trunnion roller running face profiles
Measurements of roller parameters
Trunnion roller inclinations
Kiln adjustment program and schedule
Kiln thrust and mechanical balance
Mechanical balance of the hydraulic system pressure
Drive-mesh inspection
Tyre and girth gear wobbling
Girth-gear radial run-out
Accurate measurement of kiln-shell profile Kiln-shell 3D model
Mechanical and temperature crank formation
Tyre migration and shell-ovality tests
Analysis of loads, pressures and stresses
Stiffness matrix
Advanced kiln modelling
Comprehensive test of kiln mechanical parameters
EXECUTION
All of the above outcomes are supplied along with alignment adjustment recommendations in a comprehensive report together with a series of drawings. It is worth noting that the alignment execution, like the measurement and analysis processes are done while the rotary vessel is functioning; there is no need to interrupt production processes.
