Feb 23, 2016· Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. 4.
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

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 ...

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.
