Abstract
This paper focuses on the of factors influencing calorific consumption of a vertical roller mill (VRM) and solution proposals to reduce it at a cement factory called X cement factory (for confidentiality reasons). The research aims to identify the main operational, mechanical, and material factors contributing to elevated specific calorific consumption (SCC) and to propose corrective measures for improving energy performance. Data covering a five-month production period are collected from the company’s production reports and analyzes using key performance indicators such as feed rate, moisture content, stoppage frequency, and fuel consumption. Results reveal that increased raw material moisture, frequent operational stoppages, and unstable feed rates are the dominant factors leading to higher SCC. The study concludes by proposing technical and organizational measures such as feed rate stabilization, moisture control, preventive maintenance, and improved combustion management. Implementing these measures can significantly reduce calorific consumption, enhance energy efficiency, and promote sustainable cement production.
