How to Increase VMA - Memphis
Adding an intermediate sized coarse aggregate with cubical shapes will disturb the larger particles from lying flat, one on top of the other. The VMA will increase. The crushing operation can make a difference. Examining the feed rate, cone settings, etc. is beneficial. Vertical shaft impact (VSI) crushers tend to produce more cubical particles than cone crushers. Conclusion Obtaining adequate ...
