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

The raw mix is made into fine powder after the grinding process. Raw mill industrial fans are required in the grinding process. Raw mill industrial fans are used to carry the gas and the raw mix. When heavy wheel type rollers are used, large raw mill fans are employed. Centrifugal process fans are also used extensively in other grinding process.

Raw mill is mainly used for grinding cement raw meal in the cement factory production process. It is also suitable for metallurgical, chemical, electric power and other industrial mining enterprises to grind various ores and other grindable materials. Cement raw meal is a mixture of various raw materials before cement calcination.

The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.
