Abstract: Currently in the cement industry, the trend is toward ever increasing grinding capacities of individual grinding plants. As a result, plant availability and optimized maintenance concepts are becoming more and more important. A modular mill concept allows the continuation of mill operation even if one roller is not.
II. INTRODUCTION. Since the introduction of vertical roller mills (VRMs) in cement production the importance of this comminution system has steadily increased to the point where the technology makes up more than 66% of raw and cement grinding systems sold since the turn of the century in the United States and Canada.
