Laser Alignment of Rotary Kiln
Dynamics Engineering performs laser-based alignment surveys and correction for rotary kilns — cement kilns, lime kilns, and industrial rotary dryers. Our field alignment service identifies shell ovality, tyre migration, pinion gear wear, and centre-line deviation, then recommends and executes precise corrections that extend kiln life and improve thermal efficiency.
A misaligned kiln causes accelerated tyre and riding ring wear, shell flexing, refractory damage, and increased drive power consumption. Early detection and correction avoids these costly consequences.

Accuracy a Traditional Survey Cannot Match.
Traditional piano-wire and optical alignment methods are slow and limited in accuracy for kilns operating hot. Laser measurement systems capture the true kiln axis under load, identifying deviations as small as fractions of a millimetre across spans of 50 metres or more.
Precise alignment data enables targeted corrections — minimising unnecessary work while maximising the improvement in kiln mechanical condition.

How We Align a Rotary Kiln
Laser measurements taken at each pier; tyre run-out, shell crank, and centre-line deviation recorded.
Survey data processed; deviation from true axis calculated; support roller loads assessed.
Support roller adjustments made to specified positions; pier shimming or machining carried out as needed.
Post-correction laser survey confirms alignment achieved; full report issued with before and after data.
What is rotary kiln laser alignment?
Laser alignment uses precision laser measurement instruments to survey the centre-line of the kiln shell across all support piers, identifying any deviation, crank, or pier settlement that is causing uneven loading on tyres and rollers.
Can kiln alignment be done while running?
Yes — we perform hot kiln alignment surveys while the kiln is in operation, capturing the true running condition. Cold surveys during shutdown are also offered for detailed shell and tyre inspection.
How often should a rotary kiln be aligned?
Industry best practice recommends an alignment survey every 12 to 24 months, or after any significant event such as pier settlement, refractory replacement, or tyre or roller changes.
