Product – V-cast Grinding Elements for VRM
Location – A cement plant in South East Asia
Client – A specific country plant in the region
Result – 3.5 times improvement in Life of Wear Segments as compared to High Chrome
The following case study demonstrates Vega Industriesโ expertise in providing productive and sustainable solutions for Mill product performance and quality with the help of Vcast Rollers.
This plant is into 100 % GGBS Grinding, with max mill output of 155 TPH; which would drop continuously with the increasing wear on the grinding element. This deterioration in performance would go to as much as:
โข About 5.5 % reduction in mill output
โข About 7.0 % increase in power/energy
These elements would need to be hard-faced every 2000 hours, with the wear profile over the period showing patterns as under:
โข Study of Application
โข Supply of Vcast Rollers
โข Recommendation for correction on Dam Ring, Support Ring, Roller Positioning
โข Operational recommendations for Sustainability in mill product quality โ especially the blaine and residue on 45 microns
โข Significantly improved wear life of over 6500 hrs
โข Increase in Mill Output by 5 %.
โข Reduction in SPC by 5 %
โข Output Reduction and SPC Increase within allowable limits of 5% over the significantly increased life of the element
