The FC Bond Work Index Test Ball Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bond's Method of Crushing and Grinding for determination of the Bond Index is included with each mill. CEMTEC uses this method for designing rod and ball mills. The comminution performance is, just like the desired comminution step and the production capacity, crucial for determining the required mill size. The necessary minimum sample quantity is 15 kg. The test simulates a closed grinding circuit in a standard ball or rod mill.

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.

The large grindability means the raw ore is hard to grind, which has larger wear on the liner and the grinding media of ball mill and larger energy consumption. Therefore, the grindability directly influences the grinding efficiency of ball mill.

Ball mill sizing was less critical as it would not significantly impact the general layout of the plant or the dimensions of the surrounding structure. As a result, SA designed a test work and reporting procedure which focused on delivering the highest quality SAG grindability results in the shortest period of time.

The design of rod and ball mills is still carried out with the Bond ball mill and rod mill grindability tests. As discussed earlier in this paper, it is important in this case to match the reduction size of the test to that desired from the industrial mill. As such, primary ball mills should be designed with the rod mill work
