VertiMill Sizing Example - Mineral Processing & Metallurgy

This was a case study for an expansion of a 2200 TPD SAG Mill operation. The client wanted to increase the plant to 2700 TPD @ 30um. Some plant samples were taken, work indexes obtained and data simulated. As it turns out a single 3000HP Vertimill would get that done. The applications of the VERTIMILL continue to expand in number. The variety of applications being tested and operated are ...
