Kiln Shell replacement
The kiln shell replacement process can be broken down into the following steps: layout, removal, installation, alignment and welding. Shell layout The layout of the kiln shell to be removed is a critical step as it determines the amount of shell to come out, in what sequence and in what sizes. In this step everything from crane capacity and

Rotary Kiln – mechanical issues
With increasing temperature the mechanical characteristics changes. When the kiln becoming hotter and hotter steel lost the strength: At 400, steel has lost 50% strength. At 500, steel has lost 60% strength. At6400, elasticity limit is exceeded ant it will never get back to its original dimension even if temperature decrease.

Mechanical Kiln Monitoring MKM System
The MKM System is an on line measuring system for rotary kilns with more than 2 Stations to detect abnormalities during operation, which can lead to mechanical failures. The main objective is to detect thermal or permanent cranks in the kiln shell, loss of relative movement on kiln tires and problems in axial movement at an early stage.

Jun 22, 2018 Rotary kilns run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance. One of the main maintenance works on rotary kilns is tyre and roller surface machining and grinding works which can be done while the kiln works in full operation at speeds up to 3.5 rpm.
