Coating thickness protection in the burning zone of a rotary cement kiln during operation is important from the viewpoint of the kiln productivity. In this paper, an integrated model is presented to estimate the coating thickness in the burning zone of a rotary cement kiln by using measured process variables and scanned shell temperature.

Overcoming Challenges with Rotary Drums

Overcoming Challenges With Rotary Drums

When using a rotary drum, there can be a number of challenges that many processes face depending on the material. Three of the most common are buildup, corrosion, and abrasion. Keeping these challenges under control will help to ensure that a rotary drum, whether a rotary dryer, cooler, kiln, or granulator, will last to its fullest potential.
