Reliability assessment of the vertical roller mill based on ARIMA and multi-observation HMM Qiang Wang 1,2, Yilin Fang *, Zude Zhou, Jie Zuo1,2, Qili Xiao1,2 and Shujuan Zhou1,2 Abstract: Online running condition monitoring of the vertical roller mill (VRM) is signifi-cant to assess the equipment performance degradation and reliability.
The vertical mill integrates crushing, drying, grinding, and grading transportation. It is suitable for material grinding in cement, electric power, metallurgy, chemical, ore and other industries. It can produce 10-50 tons of materials per hour. Different types of products meet the needs of customers for different materials.
mills, in the vertical roller mill the separator is inside the machine and only fine and rejected materials can be collected. The feed is calculated assuming a reasonable circulating load in the range of 8 – 12. The graph (Figure 2) illustrates the two Tromp Curves achieved with MA.G.A./VM 10 and without any grinding additive.
Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
