    Aug 17, 1971 The dry raw mix is pneumatically blended and stored in specially constructed silos until it is fed to the pyroprocessing system. In the wet process, water is added to the raw mill during the grinding of the raw materials in ball or tube mills, thereby producing a pumpable slurry, or slip, of approximately 65 percent solids.Aug 17, 1971 The dry raw mix is pneumatically blended and stored in specially constructed silos until it is fed to the pyroprocessing system.

With a roller mill, a product is compressed and reduced between two counter-rotating rotating rollers. A major advantage of this process is that the proportion of fine particles powders or dust remains minimal compared to other grinding principles and that a nice homogeneous grain-size distribution is achievable.The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh ton of raw mix whereas the VRM motor uses 7 -

    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 raw mix is fed into a circular storage unit called a raw mix storage.

In many cases, dry grinding is a very simple process, often only requiring a few steps. Dry grinding is generally much less expensive than wet grinding, the other popular grinding method, but it doesnt work as well for some tasks.
