Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns.
The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.

The costs for mini-mill producers are much more responsive to changes in market prices due to the shorter timeframes on which mini-mills purchase their raw material inputs—typically on a monthly basis. As can be seen in the chart below, the costs of a mini-mill are more volatile when compared to that of an integrated producer.
Introduction : Vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles.Vertical roller mills are widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve supplies of these materials.
In this study, in order to evaluate and compare the performances of these cement grinding technologies, industrial scale data were collected from HPGR-ball mill, VRM, Horomill and multi-chamber ball mill closed circuits. The grind abilities of the raw materials of all circuits were varying in .
Thereafter, each sample was separately ground in two types of mills. The first milling is done with a ball mill which is constituted a cylindrical chamber with horizontal axis and a capacity of 20kg. It was used to prepare cement samples with a fineness primary. The second milling was performed by using the HERZOG mill in order
