    01/07/2015· Wet milling. Both fluid energy and ball milling techniques involve size reduction of drug particles in their dry state. The extent of size reduction achievable in these dry milling techniques is limited to a few micrometers . It was reported that when the solubility of a drug is very low, down-sizing it to the micrometer range is insufficient to increase its dissolution rate and gastro

  • Operating and Troubleshooting a Grinding Circuit

    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
