Raw Mill In Cement Plant,Cement Making Plant

This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area of a unit mass of cement. The rate of initial ...

cement manufacturing process is to supply the downstream burning process with a raw meal whose quality and homo-geneity assures the economi-cal production of high-quality cements. This can only be achieved if the plant designers have precise knowledge of the materials that will be used (raw materials and fuels). This is the basis for purposive selec-tion of the production process, including ...

Rawmill - Wikipedia

27/02/2007  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 milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon
