Control Of Lime Kiln Ar X Base

Rotary Kiln Alignment. The continuity of operation of a lime sludge kiln requires strict maintenance control. The rotary kiln is among the largest type of moving machines made and is subjected to extreme temperatures, power failures, atmospheric conditions, varying loads, and other operating conditions which affect its wear and alignment.

    Portland cement clinker was first made in 1825 in a modified form of the traditional static lime kiln. The basic, eggcup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor
