Modeling of energy consumption factors for an industrial cement
This can be counted yearly as over 6% of global energy consumption. More than 60% of this tremendous energy has been used in the comminution units (crushers and mills) to reduce the size of raw materials and clinker 1 3. In the mid-1990s, the vertical roller mill (VRM) was introduced to the cement industry to reduce this energy usage.Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in Copper ore grinding in a mobile vertical roller mill pilot plant

The power consumption of its grinding system is about 20%-30% lower than that of the ball mill, and this power saving effect is more obvious with the increase of raw material moisture. In addition, the vertical mill and vertical roller mill i.e., VRM [3–5]. Among these devices, VRM plays an important role in cement, accounting for more than 55% of China’s cement raw meal market [6], and its performance directly affects the cost of producing cement. VRM has the functions of grinding and powder selection, including a grinding unit and an air Roller Mill Based on Experimental Method
