Rotary kilns and dryers normally play extremely crucial roles in the processes that employ them, hence the need for high levels of the machinery’s reliability can never be overemphasised.
In fact, experience has shown that the majority of problems associated with rotary kilns and dryers can be attributed to misalignment. In the same light; comprehensive hot kiln alignment ensures that rotary vessels are able to achieve maximum efficiency throughout their service lifespan, whilst eliminating unforeseen breakdowns.
Dickinson Group performs Hot Kiln Alignment in alliance with Fives FCB, a member of the Fives Group. The company’s hot-kiln alignment services results in the provision of the following:
Current rotary kiln alignment status
Condition of the tyres and trunnion rollers including tyre chairs and tyre stops
Tyre and trunnion roller running face profiles
Measurement of roller parameters
Trunnion roller inclinations
Kiln adjustment programme and schedule
Kiln thrust and mechanical balance
Mechanical balance of the hydraulic system pressure
Drive-mesh inspection
Tyre and girth gear wobbling
