raw mill and cement mill for cement production process
A rawmill 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 rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

Cement Production: Raw Meal Production in Steps
Additives such as clay, sand or iron ore result in the desired chemical composition. The MULTIDOS® H weighfeeders and MULTIDOS® VPD apron feeders feed the various materials into the raw mill accurately and reliably. The raw meal is then homogenised in the blending silos. Finally, flow gates transport it to the next process step.

The major processes involved in production are excavation of limestone crushing of limestone, preparation of other raw materials, grinding of raw materials in the raw mill, storage of raw meal in a raw mill silo, blending of limestone powder to control CaCO3 percentage, burning of raw meal to form clinker, grinding the clinker with gypsum in cement mill and storage of cement in silo packing and
Manufacturing process | Lafarge Cement, concrete
The raw mill contains two chambers, separated by diaphragm, namely a drying chamber and a grinding chamber. The hot gases coming from a preheater (preheater / kiln system) enter the mill and are used in raw mills for drying. Then the drying materials enter the grinding chamber of raw mills for fine grinding.
Process Fans Used in Cement Industry Reitzindia
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.
