What is meant by Closed circuit Cement Mill & Open circuit Cement Mill. Exactly what it says - coarse material goes in at one end of an O/C Mill and comes in a finer state at the other end; in a C/C system, the coarser fraction of the product is separated in a classifier and returned to the mill input for further processing. 6.

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement.
The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness. That is why high quality grinding balls with high hardness over the entire section are used during grinding materials in tube mills in this industry.
Practices that maintain the inherent capability of the equipment. Deterioration begins to take place as soon as equipment is commissioned. In addition to normal wear and deterioration, other failures may also occur. This happens when equipment is pushed beyond the limitations of its design or operational errors occur. Degradation in
The presence of moisture in the climate would be damaged cement and it becomes useless material. Storing cement must be kept in an airtight workplace or worksite in the godown. The intake of moisture from climate also depends on the quality and quantity of cement. For this, extra care must be taken to keep the cement fresh and well.
