There are usually four kinds of VRMs in the cement production line, including raw meal mill, coal mill, Clinker Mill and cement mill, and the vertical mill occupies a large energy consumption unit. A process simulator was used to study an industrial-scale vertical raw mill (VRM) with 65.4% energy efficiency. The paper proposes further a new model based on grid partitioning, Assessment of the thermodynamics efficiency of a cement vertical raw

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 Most new cement plants utilise vertical roller mills (VRM) for raw material grinding and preparation. Taking a step-by-step look at the entire roller milling process, Kline Consulting recommends routine VRM optimisation International Cement Review

Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.A raw mill is a key piece of equipment used in a cement plant to grind raw materials into a fine powder. It works by crushing and grinding materials such as limestone, clay, and iron ore into aHow does a raw mill work in a cement plant? LinkedIn

The raw mill has a capacity of 240,000 kilogram- material per hour. Also, both exergy and exergetic efficiency of raw mills from three literature sources were investigated and compared with the simulation results from Aspen Plus process model. The results were subjected to statistical analysis using ANOVA. The exergy efficiency for the raw milland 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.

For constructing a CL dedicated to the VRM circuit and predicting motor power and outlet temperature (as indicative energy factors), a dataset was collected from one of the vertical roller raw mill circuits (line 2) in the Ilam cement plant. The critical operating parameters gathered during the standard operation are summarized in Table Table1. 1Modern cement plants trend for the usage of vertical mill in cement grinding because of its many advantages of lower energy requirements, higher feed rates, simple layout (drying, grindingOperational parameters affecting the vertical roller mill
