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.mill level, combined in the roller unit. No swing-out cylinder is needed for maintenance purposes.

Vertical Roller Mills LNV TECHNOLOGY
Vertical Slag Mill: A vertical slag mill is used for grinding and drying water quenched slag that is generated by blast furnaces into an active material which is then added to the finished cement. Note: Feed moisture <20%, feed size <10mm, final product moisture≤0.5%, final product fineness <4200cm2/g～5000cm2/g, power consumption <33 kWh/t.As a result maintenance downtime is reduced and work is easy and safe.
