3 Common Problems Seen in Lime Kilns Kiln Technology
2021年8月23日 — 2. Shifting calcination zones. The ideal area for calcination to occur is in the center of your rotary kiln. If the heat zone shifts too far up or down the kiln, it could significantly affect output. The main reason this could happen is improper airflow. If the calcination zone is shifting upwards, too much air is being used.

Cement kiln - Wikipedia
Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. [2] [3] [4] The basic, egg-cup 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
