Modelling: Transfer size limits

For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 10:15 (1:1.5). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill power (1:1.5 in this example).

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 ...
