2.6 Vertical Roller Mill Internal Modification
Process: The vertical roller mill was modified for raw meal grinding because of the
movement inside is different in terms of speed. A high speed horizontal attrition
mill for dry grinding with a higher Rotation per minute (RPM) is a used to conserve
energy by optimizing the electricity level from the variable frequency drive which
changes the direct current (DC) to alternate current.
Explanation of Cost Analysis using ROI and CBR for VRM internal
modification
For (VRM) internal modification, the return on investment in conventional technology (non-renewable energy) was (−100.89%) and cleaner technology (VRM)
internal Modification was (−26.5%) 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) (0.0220) and cleaner technology (VRM) internal
Modification (0.76) where cleaner technology showed a higher benefit. Along with
loss in ROI and gain in cost-benefit ratio, cleaner technology also benefits by energy
saved of 120,000 kWh per year and Rs. 5.7 lakh monetary profit per year as shown
in Table 1.
2.7 Vertical Roller Mill Cement Girding CVRM Sp. Power
Reduction in OPC Portland Cement Grinding
Operational process: The older switch is a direct current (DC) switch mode power
supply change into alternate current (AC) supply modification has been done called
power reduction switch.
Explanation of Cost Analysis using ROI and CBR for VRM girt cone
modification
(VRM) Special Power Reduction in OPC showed return on investment in conventional technology (non-renewable energy) as (−119.19%) and cleaner technology
(VRM) Special Power Reduction in OPC as (−67.8%) for Rs. 1 investment. On
comparing the two technologies recorded loss in ROI. In terms of cost benefit ratio
conventional technology (non-renewable energy) (0.0341) and cleaner technology
(VRM) Special Power Reduction in OPC (0.337), cleaner technology shows a higher
benefit. With loss in ROI and gain in cost-benefit ratio the cleaner technology added
benefit by energy saved amount of 52,600 Kwh per year and Rs. 2.50 lakhs per year
(Table 1).
2.8 Variable Frequency Drive (VFD Installation)
Principle of working: Direct current (DC) is changed into alternate current (AC)
