Part Three: Raw Mill. Process of Raw Mill The proportioned raw material is feed first to a grinding mill. In the mill, particles ground in to very fine sizes. In the grinding unit, drying, grinding and mixing takes place simultaneously. Hot gas from clinker burning unit is passed into the grinding unit to assist the drying and grinding process.
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 ...
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 production …
