Review on vertical roller mill in cement industry & its
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.The quadropol® concept for coal or pet coke grinding, with adapted table speed and high efficiency separator sepol®, ensures a safety mill operation and serves reliable the kiln burning process.

Operational parameters affecting the vertical roller mill
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 this design is decentering of the outlet duct from the separator. By decentering the duct from the center of separator, it was possible to suppress the fast gas flow directly beneath the duct and smoothen the discharge of revolving airflow from the separator.

Modelling of vertical spindle mills. Part 2: Integrated models
There are three basic structures among the coal grinding, t: Air-Swept or Wet Tumbling Ball Mill, Roller-Race or Ball-Race Mill and Hammer or Impact Mill [7–10]. The type of the mill and its efficiency depend on the type of coal, its moisture, input and output fraction of the material and the grinding susceptibility of the coal.UBE Vertical Roller Mill UBE’s mill design and rich experience of more than 260 Mill installation allows us to handle coal which is combustible and volatile in nature by ensuring safety and efficient grinding efficiency.
