Bond Crusher Work Index Pendulum Test
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)

of the pendulum is raised until the energy is sufficient to break the specimen (Bond, 1947), and then the crusher work index (CWI) or impact work index is calculated. The test is generally performed on 20 rocks in the -76.2/+50.8mm size fraction. One of the strengths of the test is its ability to measure the natural dispersion in the .

Impact work index prediction from continuum damage model
An impact pendulum that follows strictly Bond’s standard for crushability measurement (Bond, 1947, Bergstrom, 1985, Tavares, 2007) has been used, which allows calculating the crushing, or impact, work index.The test consists of dropping two pendulum-mounted hammers simultaneously against individual particles of size ranging from 75 to 50 mm that are sitting on a pedestal ().

IMPACT OF PHYSICAL AND MECHANICAL PROPERTIES OF ROCKS
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 (Tavares and Carvalho 2007).
