Customer case stories

Vcastโ€“ Vegaโ€™s latest innovation in VRM, results in significant improvement in Mill Output, Wear Life and Specific Power Consumption

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.

Problem
With escalating energy costs and market demand, a Cement Plant in South East Asia felt a pressing need for highly energy efficient grinding systems which also delivered improved and consistent process and performance parameters along with long life of grinding elements.

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:

โ€ข About 5.5 % reduction in mill output
โ€ข 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:

Solution
Vega Industries presented the client with a complete 360 degrees solutions, with following intervention and solutions:

โ€ข Study of Application
โ€ข Supply of Vcast Rollers
โ€ข Recommendation for correction on Dam Ring, Support Ring, Roller Positioning
โ€ข Operational recommendations for Sustainability in mill product quality โ€“ especially the blaine and residue on 45 microns

Improved Wear Life
Demonstrated User Benefits
The clients could see the following benefits โ€“

โ€ข Significantly improved wear life of over 6500 hrs
โ€ข Increase in Mill Output by 5 %.
โ€ข Reduction in SPC by 5 %
โ€ข Output Reduction and SPC Increase within allowable limits of 5% over the significantly increased life of the element
