3 Common Problems Seen in Lime Kilns Kiln Technology

2021-8-23  One common use for rotary kilns is the production of lime (calcium oxide) by calcinating limestone, which requires significant heat to achieve – approximately 900 °C (1,650 °F). Such high-temperature processes must be handled carefully, and there are several problems that may arise if the kiln is not properly configured for this usage.
