Causes of lime kiln vibration

Sep 14, 2017 Big gear ring is the important part for the rotary kiln’s transmission system with meshing pinion gears. However, in operation of rotary kiln, big gear ring is prone to vibrate. So, to find out the cause of gear vibration and adopt the corresponding processing method is an important part of rotary kiln maintenance

    A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840 C (1544 F), but is generally considered to occur at 900 C(1655 F) (at which temperature the partial pressure of CO 2 is 1
