  • Bond Impact Crushing Work Index -Procedure and Table of

    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)

  • IMPACT OF PHYSICAL AND MECHANICAL PROPERTIES OF ROCKS

    Kick's "law" gives good results for crushing, Bond's for grinding and Rittinger's for fine grinding. Based on a large number of tests, Bond introduced a working index or comminution parameter that represents the resistance of the material to crushing and grinding. Characterization of rocks for selection of crusher can be done in different ways, and the most commonly used is Bond work index
