Course Introduction
Raw mills and kilns are the backbone of cement manufacturing, directly affecting production efficiency, energy consumption, and product quality. Operational issues in these systems can lead to serious disruptions, increased maintenance costs, and reduced output. Effective troubleshooting and process optimization are essential to maintaining high performance, reducing downtime, and ensuring operational stability.
This intensive 5-day course provides a hands-on and technical approach to troubleshooting mechanical, process, and control problems in raw mills (vertical and ball) and rotary kilns. Participants will explore real plant scenarios, failure modes, performance analysis, and corrective actions—enabling them to identify root causes and implement solutions efficiently.
