The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.

When Grounding an Electrical Panel the following applies Grounding a Main Panel. The ground bar is bonded internally when an external bond to earth is installed as described at the link for Electrical Grounding below. Grounding a Sub-Panel . Sub-Panels are grounded through the cable that provides the sub-feed circuit power.
The concentrator flowsheet begins with three rod mills operating in parallel and in open circuit followed by three ball mills operating in parallel and in closed circuit with a bank of ten 10-inch hydrocyclones. As illustrated in Figure 3, rod mill discharge and ball mill discharge are combined in the same sump and pumped to the cyclones.
