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.
Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have drying function besides grinding.

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw …
The milling process in cement plants is extremely energy-intensive. there are potential energy savings available through the use of Mill Control System (MCS). The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledge-based approach using current plant data (defined measured values).
Raw mill is the grinding equipment applied in the raw material preparation process.In the wet process of cement production, raw materials should be ground into raw slurry with a water content of 30% – 40%. While in the dry process of cement production, they will be ground into dry powder in cement raw mill.
Raw Grinding Plant. 1. Wet grinding mills such as ball mills operating either in close or in open circuit. These are also called slurry mills which are used in both wet process as well as semi - wet process plants. 2. Dry grinding mills, operating only in closed circuit, are used in dry and semi dry process cement plants.
Cement vertical mill, also called roller mill, is another raw mill commonly used in cement plants. Compared with the cement ball mill, it has a great difference in structure, grinding principle, process layout, automatic …
