PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL ROLLER MILL
The power ingesting of a grinding process is 5060% in the cement production power consumption The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills The process variables in cement grinding process using VRM are strongly nonlinear and havingThe cement vertical mill is grinding equipment developed on the basis of similar grinding mills, so it has many irreplaceable advantages, such as high grinding efficiency, low power consumption (2030% less power than ball mill), large drying capacity (simultaneously dry and grind materials with moisture up to 10%), the large particle size of grindingCement Vertical Mill Vertical Grinding Mill Vertical Mill
Application of Vertical Roller Mill in Cement Production
In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced VRMs are more energyefficient, ecofriendly, and produce a more consistent product compared to traditional grinding mills They are also more suitable for use in urban areas due to their lower noise levelDespite the growing use of vertical roller mills (VRM) for clinker grinding, very few research work is available on VRM modeling This article reports the design of three types of feed forward neural network models and least square support vector regression (LSSVR) model of a VRM for online monitoring of cement fineness based on mill data collectedOnline monitoring and control of particle size in the grinding
