The operation of the cement raw mill is a critical step in cement production. By grinding the raw materials into a fine powder, these powders can be more easily mixed with other cement ingredients and burn more evenly during the cement clinker process. Therefore, the efficient operation of the cement raw mill directly impacts the …

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum – a form of calcium sulfate – is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

The main difference to cement mill operation is the need to dry raw·feed and assure transport of stightly moist materialwithin a mill. Also, many raw materials are softer than clinker, and operations must avoid coarse residues in kiln feed that are difficult to combine in the kiln and would result in high clinkerfree-lime, and/or excessive ...
