power & increases the productivity. Worldwide references indicate the 5%
increase in productivity and 3% reduction in power consumption of mill after
the installation of PSD.
- The PSD with Expert control system results the grinding only as much as is
necessary to meet the desired specifications. This gives the benefits of better
quality of product, more productivity and lower power consumption. - The improvement in product quality also permits the reduction in C3S (alite)
concentration. Increasing C3S concentration improves early strength but
increases energy costs because the Kiln conditions required to produce it
are more demanding. Since strength targets can be more easily achieved, it
decreases the C3S level, reducing the operating costs of Kiln. - PSD helps in maintaining proper Particles Size distribution of finished cement
which also results to the relatively low water demand in mix. The less water in
the mix results in higher early strength. - PSD helps in higher one-day strength of mix as compared to Blaine parameter
controlled manufactured cement. - Assists plant operator during product change over or when developing new
grades. - Extracts process variations free from sampling errors.
- Reduces the man power cost and dependency on human intervention.
4.8 Conclusion:
The benefits of on line particle size analyzer attributes following key factors
- It is observed with aged clinker, adding the more gypsum, Fly ash / Rice husk
Blaine can be increased but Particle size of cement not changing. while quality
of cement decides with Particle size not with the Blaine. - Using the particle size analysis, we can optimize the power consumption and
productivity of cement and consistent quality of cement fineness can be
maintained. - Overgrinding can also be minimized.
