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 Features of vertical cement mill. Vertical mill can dry and grind materials with moisture up to 10% at the same time; Vertical mill has simple processing, compressed structure and small building space.

Chapter Six: Some Operating Guidelines Vertical Roller Mill
Many ask me about the procedures for starting and operating the vertical roller mill, a grinding machine used in the cement industry. I have to confess that answering that question is complicated.a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical roller mill did not take place until the beginning of the 1990’s. 1935 The first Loesche mill for grinding cement clinker, an LM 11, was commissioned in Joao Pessao, Brazil.Loesche Mills for Cement and Granulated Blast Furnace Slag
