    The power ingesting of a grinding process is 50-60 in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40 associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time.

    However, the energy utilization rate of tube mills is only 2 ~ 20 , which is very low. With the continuous development of grinding technology, there are two kinds of cement grinding equipment with lower energy consumption, one is vertical roller mill, and the other is roller press.

    Grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.

    Drive systems for vertical roller mills. Capacity of cement new production lines has steadily increased over the last years. Reduction of investment costs is one of the most important driving factors for this trend. Because of simple scalability and low energy consumption, the vertical roller mill is a key part for single mill cement lines.

    The vertical pre-grinding mill makes use of pressing force and shearing force for material grinding. It offers better grinding results than roller mills. When used for cement raw material and cement clinker pre-grinding, the pre-grinding machine can increase production capacity by 100 and 50 , respectively, while reducing electricity.

    The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments.

    Air Volume Control. The differential pressure of the vertical roller mill is generally controlled at 5000~7000Pa to ensure the proper air volume. The change of the pressure difference within the mill is mainly affected by the feed amount when other conditions are constant. Therefore, the feed amount should be stabilized.

    The vertical roller mill (VRM) is popular and widely used for grinding of coal and raw materials. The vertical mill is energy efficient with low specific wear rate. Vertical mill supports drying of the feed material, grinding, separating, and material transport inside the mill.
