  • 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
