Challenge details:

Rotary kiln is an inclined, rotating cylindrical device used for continuous high-temperature processing of bulk materials across various industries. The gearbox and support rollers are crucial for ensuring the efficient rotation and stability of a rotary kiln, impacting the overall performance and longevity of the equipment. High ambient temperature ~90°C which reaches up to 110°C near the support rollers along with low rotational speed ~ 1-2 RPM, limits the possibilities of carrying out effective condition monitoring practices.

Currently, the ultrasonic monitoring methods employed are proving to be inadequate due to the high-temperature environment, which affects the reliability of the data collected. Additionally, the lifespan of bearings has been reduced recently, which is attributed to maintenance issues and has resulted in breakdowns leading to complete stoppage of the production line. The goal is to develop a comprehensive monitoring system that must be robust enough to handle these conditions and provide accurate data to prevent downtime and facilitate proactive maintenance strategies.

Addressing this problem is critical for maintaining the efficiency and reliability of the kiln operations, which are pivotal in the production process. The solution must be tailored to handle the specific challenges posed by the low RPM and high-temperature conditions, ensuring continuous and effective monitoring of the kiln"s critical components.
