Operating and Troubleshooting a Grinding

In the operation of a grinding circuit you are managing several pieces of equipment as a single unit. If you make a change in the ore in the fine ore bin, that change will be reflected through the entire grinding process and beyond into the rest of the concentration system. The first thing that an operator will have to learn is to be able to tell when the rod mill is, or isn't, grinding fine
