Why in the cement production, why the fineness of the rough but the surface area is high?
With the cement additives, the cement fineness ran thick, it seems unreasonable, but this situation does occur. General cement additives have a good grinding auspicious, good grinding will improve the flow of cement ash, when the grinding material flow rate is much faster than with the milling efficiency, the cement out of the fineness will run rough , For open grinding, will directly cause the cement product fineness, can not increase production.
For closed-circuit grinding, will increase the burden of the separator, such as the lack of processing capacity of the separator, the cement product will cause the fineness of running thick.
If there is a rough phenomenon, the entire process should be analyzed, the cement mill system, the conditions can be calibrated mill, and the actual measurement of cement mortar flow rate.
The proportion of the length of each warehouse, such as the average bulb, the filling rate is low, the gap between the wide gap, the ventilation speed and other reasons are May cause running rough phenomenon. But also to investigate the circulation of the separator load and efficiency, adjust the air volume and speed of the separator, as far as possible through the separator to adjust the fineness of running rough problem.
