Inverter controlled iron ore ball mill grinding (3 replies)
Please join and login to participate and leave a comment.
Does anyone have a couple of examples where iron ore is being ground using a ball mill with an inverter for mill speed control?
And if you do, can you offer any commentary on how successful, in technical and economic terms, that approach is proving to be?
I ask on behalf of a Japanese company that wants to build a better business case for a proposal they are want to make.
Many thanks.
