The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.P80 = 25400 x Oss x (0.04Wi + 0.40)

## bond work index ball mill design and safety factors

A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant. Where possible, it is carried out on a sample of ore that is typical of the proposed feed to the plant. The BBMWI is then used in the design calculations of the new grinding circuit. A BBMWI may also be used in the simulation and subsequent optimisation of existing mill(s) and the associated ...
