Explanation of Cost Analysis using ROI and CBR for (VRM) inlet duct
Modification
Vertical roller mill (VRM) machinery had a huge amount of modification in this
cement industry. Considering the (VRM) inlet duct modification the return on investment in conventional technology (non-renewable energy) was (−79.3%) and cleaner
technology (VRM) inlet duct Modification was (−93.3%) for Rs. 1 investment. On
comparing the two technologies there is a loss in ROI. In terms of cost-benefit ratio,
conventional technology (non-renewable energy) (0.2341) and cleaner technology
(VRM) inlet duct Modification (0.0640) and in terms of cost-benefit ratio, conventional technology shows a higher benefit. But in cleaner technology, energy conservation was done due to less use of pressure and temperature, sensors and automated
flow meters were attached for more accurate readings leading to energy saved as
58,400 Kwh per year and profit of Rs. 2.77 lakh per year, though ROI showed loss
as shown in Table 1.
2.5 Vertical Roller Mill Grit Cone Modification
Older technology
Vertical roller mill is used directly and there were no modification done so if there
is solid waste it should be recycled at the end of the process, due to this process again
the operational cost can be higher due to energy use.
Vertical roller mill Grit Cone Modification
The process of grit cone is used in between the vertical roller mill to separate the
particles in two different way coarse and fine particles High efficiency and sharpness of separation, using of different separation of materials of different grain size
distribution, Easy for adjustment of the fineness of the product, Low specific power
consumption, High drying efficiency within the separator, Cooling of the material
with ambient air is also made has an add-on technology.
Explanation of Cost Analysis using ROI and CBR for VRM girt cone
modification
Analysis of (VRM) grit cone Modification, the return on investment in conventional technology (non-renewable energy) was (−72.1%) and cleaner technology
(VRM) grit cone Modification was (−30.4%) for Rs. 1 investment. On comparing
the two technologies, both show loss in ROI. In terms of cost benefit ratio conventional technology (non-renewable energy) (0.3115) and cleaner technology (VRM)
girt cone Modification (0.762) and cleaner technology showed a higher benefit (Table
1). Despite the loss in ROI and cost-benefit ratio of cleaner technology, the added
benefits like energy benefit of 95,900 kWh per year and a profit of Rs. 4.5 lakhs per
year was recorded. Advantage of Vertical roller mill Grit Cone Modification: Less
maintenances and operational cost, High energy efficiency, recycle the fine particles
