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 ...

TECHNICAL SOLUTIONS FOR GRINDING

GRINDING OPERATIONS GRINDING Raw balls are usually ground by rolling under pressure between a cast iron disc (rill plate) and a vitrifi ed grinding wheel. The grit size of the abrasive depends on the dimension of the balls and process requirements. In general, smaller balls require fi ner grit and harder grade, larger diameter balls require coarser grit and softer grade. Grit size ranges from ...

THE MODE OF BALL MILL OPERATION

 · Waterfall – the grinding balls move along a circular trajectory and change it further under gravity. Supercritical mode – centrifuging of the total grinding media volume. Shredding of material in cascade (figure a) mode occurs because of crushing and abrasive effects of grinding balls. This is the most common mode used during operation of rod mills, ball mills with central unloading and ...
